The core advantage of the double root of double-cream tomato cultivation, which is the new high-yielding model promoted by the main of the facility's large-scale and field-scale production, is that the two-layered roots are co-smoking, and the synchronised results of double-creaming, completely circumventing such pains as the premature decay of the traditional monocreatic root-planting system, the vagaries, the inadequate supply of mid- and post-term nutrients, the uneven size of upper and lower fruit, and the frequency of broken ears. The rational implementation of standard, process-based planting measures will effectively increase the resilience of the tomato population, with an increase of 30 to 40 days in the harvest cycle, an increase of more than 20 per cent in the acre production, a substantial increase in the integrity of the fruit, a parallel increase in the rate of refined fruit, and an adaptation to early spring huts, autumn delays and winter seasons whole-product vent cultivation is a core practical technique for stabilizing production gains at scale bases。
I. Optimal selection of suitable varieties, optimization of plots and construction of a strong productive base
The long, active branches and the heavy loads of the adjoining fruit are the exclusive plant for double-cream cultivation, and the suitability of varieties and plots directly determines the subsequent growth rate and overall capacity. The preference for varieties is to reduce the risks of plant management from the source by using long, robust, infinity growth habits, resistance to disease, continuity of sit-in fruit, high-resistence storage of fruit, high-quality hard- and hard-to-spruce varieties of tomatoes, which are not easy to grow and fall, and by strictly circumventing old varieties of self-capture, weak and susceptible viruses。
Land parcels give priority to the selection of land plots with deep-dry and pyrotechnic structure, sufficient organic content, easy-to-drive, medium-land or sandy plots that have not grown eggplant crops for more than three years, and are determined to avoid low-lying water, salinized salin, and reconnected to super-marked plots, reducing the probability of outbreaks of endemic diseases from their root causes. A deep-tilled global tillage was completed 15 days before planting, with depths ranging from 25 to 30 centimetres, simultaneous cleaning of the remaining weeds and diseased branches in the fields and cutting off the insects from winter boarding carriers. Accompanied by high-quality, decomposed farmers ' fattening complex fats, organic fat for each acre of deep-droping fertilized commodities ranging from 4,000 to 5,000 kg, composite fattening 40 kg of potassium sulfate, 10 kg fattening of small and medium-sized elements, and 2 kg of biobacterizers, are evenly ploughed into deep soils. It is followed by a high diaphragm, 25 centimetres high and a distance of 140 centimetres, accompanied by drip-drive belts, so as to level the accelerator, the membrane edges are compact and evenly balanced, and it is suitable for subsequent double-dicking of the cranium cover to ensure that the roots are rooted in the subsequent stratification。
Ii. Precise seedlings, standard density planting, and firming up the roots of the twin chickens
The seedlings are the core pre-positioning conditions for the formation of double chickens and for the subsequent steady production of the proteins, with the weak and the very easy to produce an imbalance in the growth of the chickens, difficulties in the emergence of secondary roots and a sharp decline in the number of adhesive fruit. The integrated management of hot water fattening during the seeding period is strictly controlled, using a specially designed glare-based soilless seedling model, which cultivates a 15- to 18-centimetre-high, four-leave-to-five-heart, strong-brained, green-rich leaves, thick roots, age-appropriate seedlings free of disease and disease, and eliminates high-foot weak, old and ill seeding。
The early spring sheds set the weather-free hours of the day, the autumn seasons avoided the high-temperature and high-light hours of midday, strictly followed the principle of shallow planting without heart or earth, and strictly controlled standard planting density, with a distance of 70 centimetres and 40 centimetres, precise planting of 2,300 to 2,500 units per acre, not too dense to be too high, to avoid the loss of wind and wind during later periods. After planting, firm roots of seed water are poured through, and small amounts of acidated water soluble and weak root agents can be added to the water, which is fast and slow to take root. Three to five days after planting, visits are made to fill the seedlings in time to ensure that the whole field is smouldered and consistent, and to establish a solid and nurturing basis for the subsequent unification of double-cranium plasticization and synchronous synchronisation。
Iii. Precision of double chicken plastics, standardization of chicken bacon, setting up a framework for high-yielding strains
Double chicken plastics are at the heart of the whole planting technique, and operational timing, tactics, and weak control can lead directly to rotting secondary roots, atrophy of the sides, and a decline in the whole plant. The whole journey follows a standardized process of raising the master chicken, then keeping the chicken, pressing the chicken in due course, and stratification of bacon, and the whole course of the day is clear, avoiding a rain wound and infecting the chicken。
The seedlings are then brought into normal life, with only the backbone of the plant being retained as the first chicken, while the rest of the low-level spas are wiped out as soon as possible to reduce the consumption of ineffective nutrients. When the plant grows to the point where the first chorus is fully visible, the flower-free deformity is sprouted, a strong, stretching, disease-free, strong side branch is selected as the second chicken, with all the remaining low-side sprouts and non-functional branches completely cleaned out, and a standard double-circle structure is constructed to ensure a reasonable distance between the two chickens, parallel and parallel growth, and balanced supply。
A double-root chicken operation is formally initiated until the chickens are reserved for natural growth to a standard length of 50 cm. In advance, open the edges of the membrane on both sides of the plant, and dig parallel to the two tomato lines, two arc shallow trenches of 20 centimetres long, 10 centimetre wide and 3 centimetre deep, with the earthy grooves of the gutter shredded with soft and soft pieces. Carefully lay the mid-cranium flatly at the bottom of the ditch, and the point of the chicken is sprawled in the direction of the poles opposite, with a light swing throughout the journey, and it is strictly forbidden to bend and crush the skin of the contusion. Small water is slowly watered in the ditch once the water is fully immersed, it is evenly covered with fine-tide soil, it is only left to the top of the tip of the cranium to display normal light co-operation, and it is possible for seven days or so to produce a large number of non-stable roots, forming a two-stereo-sort system of water-sorting at the top, and at the bottom, with its old roots, to strengthen the capacity to fully absorb nutrients. Follow-up is timely for the synchronous chording of chickens, keeping both chickens in a straight line of orderly growth and avoiding entanglements of light and depression。
Iv. Quantified management of water fertilizers, as required, supplementary folic nutrition, and steady chicken promotions
With a large total biomass of double-creamed strains, a large chain of broods and a high rate of nutrient consumption, management of water fertilizer must be provided over a period of time, on a demand-driven basis, free from flooding, blind application of nitrogen fertilizer, strict protection against long flowers, broken roots and early chicken decay. Cultivation periods are dominated by steady water control, which does not follow fat, light water, and promotes deep grounding。
When the double chicken plastics are finished and the secondary root is fresh, they enter the critical period of acupuncture, mainly to balance the potassium fattening of nitrogen phosphorus, which is 5 kg per acre of high nitrogen-heated potassium fattening with drip irrigation, 15 days per day, in combination with small water effort, to keep the soil dry and wet, and to assist both chickens to grow in parallel and fat and fat. Upon entering a continuous flowering season, nitrogen fertilization is strictly controlled, high-pretium perchation is increased, water soluble fertilizer is simultaneously pursued for each poaching fruit, six to eight kilograms per acre of potassium sulphate-based water is applied, calcium is sequestered, magnesium is sequestered with a combination of trace elements, effective prevention of umbilical disease, fisssure, and cedar cedars。
High-temperature and high-light periods of dry water are used early and late, low-temperature and weak-light periods are used to reduce water control, and soil moisture is always maintained in a stable manner, and physiopathies are not induced by dry and wet. After a decline in the activity of the root system in the mid- and post-growth periods, the phosphate potassium with amino acid folate is sprayed every seven days, with both sides of the leaf flatly applied on the opposite side, quickly replenished against premature decay, increased phototransformation efficiency and rapid expansion of the coloring and sweetness of the force fruit。
V. Scientific regulation of the field environment, fine daily care and optimization of the micro-environment
The precision control of the four environmental elements of temperature, light, water and gas under the facility cultivation model, which is adapted to the growth habits of the double-cranium plant, is an important safeguard for stabilizing the protein. Temperature stability in day sheds is contained at 22 to 28°c, scientific temperature protection at night is maintained at 12 to 15°c, reasonable temperature differentials at night and day are maintained to accumulate nutrients, and cold seedlings are protected against temperatures above 35°c and temperatures below 10°c at night。
In a timely manner, the shed is humid with reasonable ventilation, with windows open around noon on and around sunday, and the relative humidity of the air in the shed is stabilized at 60 to 70 per cent, so as to prevent the induction of fungi and bacterial diseases in high-humid closed environments. Keep the mural clean and light all the way, clean up the dust and dust of the balconies in a timely manner, increase the permutation rate and ensure normal light co-operation of the submersible foliages. In day-to-day care in the field, the base leaves, yellow leaves, sick leaves, invalid ears are regularly removed, four to six flat and high-quality fruits are kept per ear, deformed in a timely manner, insects and insects are removed, wasteless nutrients are reduced, and nutrients are concentrated on the growth of healthy fruit. At the same time, the staves in the sheds were reinforced to guard against the high amount of late-term staggered fruit leading to the fall of the cranium and to guarantee the integrity of the field。
Vi. Green integrated pest control, prevention in the whole course, protection of stable production quality
The puddles are thick and isolated, their small environment is more humid, and they tend to breed common diseases such as greyy disease, premature disease, late disease, frescosis and root disease, while they are vulnerable to pests such as white ticks, aphids, tea mites and cotton bellworms, and the principle of prevention, physical preference, green support and scientific medicine must be upheld。
Pre-plants are closed to high-temperature dormitories for disinfection, with biobacterizers distributed in the soil and insect eggs from the soil. (b) to maintain reasonable ventilation in the field for a long period of time, to clean up and destroy in a timely manner the pathogen of the leaves and fruit of the disease outside the field and to cut off the transmission chain of the disease. Physical control is accompanied by the installation of 60-bit inter-vermin nets in the open and wind vents to prevent pests, and the significant reduction in the base number of worms in the field by cedars, blue-board baiting aphids, white powder lice, parrots. When necessary, special biopesticides with low toxicity, low residues and registered compliance, ecopharmaceutical agents are selected to be used for alternative spray control, in strict compliance with the safety interval and complete phase-out of the drug seven days before the harvest, to ensure the green safety of tomato fruit and compliance with the listing standards。
In conclusion, the core of the high production of tomatoes is good breeding, bottom-up seeding, scientific planting, precision double-root plastics, periodic water fertilisation control, environmental precision control, green pest control and whole chain of synergies. A simple set of technologies, low input costs and an intuitive increase in the quality of production, and strict regulatory measures against the target by a large number of growers, can easily lead to longer tomato harvest periods, higher yield rates and steady growth in acreage efficiency, with regularization and extension applications for various size-based tomato plantations。
