Technical opinion on management of vegetable production throughout the province, 2026
Delays in the planting of winter vegetables due to the prolonged rainy season last fall continue to have a negative impact on production. The management of vegetable production in the spring must focus on promoting weakness and strengthening, and science should be geared to disaster prevention and mitigation and ensuring a stable and safe supply of vegetables。
I. Strengthening management of vegetable production in winter
Vegetable management in winter is to focus on “depressive growth and resistance to decay”, to coordinate nutritional growth and reproductive growth, to regulate the environment in science, to rationalize fattening, to capture pest control and to improve overall productivity。
(i) vegetables in winter facilities
1. Environmental regulation. Vegetables are growing at a suitable temperature of 20°c ~ 32°c, with temperatures at around 15°c in night sheds. An integrated approach should be taken, with a view to rationalizing ventilation time, reducing the humidity in the shed and reducing the incidence of disease. As the external temperature rises, it should be kept warm as early as possible, with longer periods of light. In rain and snowy weather, exposure to plastic sheeting prevents wet ice。
2. Fertilizer management. In the light of the weather, water is poured out in the morning, and the application of fertilizers follows a small number of times. Vegetables may be selected for high potassium and leafy water soluble at 2-5 kg per acre with biobacterizers, fish protein, crustaceans, algae acid and amino acids. Potassium dihydrophosphate and amino acid nutrients may be sprayed on the leaves if necessary。
3. Plantation adjustment. Vegetables such as eggplant fruit and melons should be prepared in a timely manner, such as chickens, whole branches, grafts, rinsing, removal of old leaves and vermin, improvement of the group's ventilation and maintenance of the balance of plant berries. In case of unusual weather, the early harvest of commercial fruits reduces the capacity of the plant。
Plumbing fruit. Vegetables such as eggplants may be pollinated with bear bees or artificially assisted. The rational use of plant growth adjusters in cold seasons promotes the growth of sit-ins and fruits。
5. Patient control. Integrated application of eco-regulation, physico-probability, biological control, etc. Insects are lured by yellow-blue plates, insecticidal lamps, etc., and insects are prevented from entering through entrances and vents by the installation of anti-worm nets of more than 60 inches. Priority has been given to biological control, the timely release of natural enemies such as the ravioli bee and the east asian bouquet, the spraying of the green fungus of the gold turtles, the bacterium sprouts and the hatz mucus. Priority is given to dust and smoke control. Controlling the spread of the virus through the application of such agents as ninganicillin, sugary mushrooms, hydrochloric acids。
(ii) vegetables in winter
1. Garlic. Garlic is a fertilizing crop that uses “three fats and three water” for scientific application, which promotes growth, drives water fattening, and increases water fattening. Based on soil conditions and rainfall, science refuelles, pushes and swells. In combination with water, urea is usually applied 10-15 kg per acre to promote leaf-leave growth and root system development; lumbers and sprouting are typically applied 15-20 kg per acre of balanced compound fat, which promotes division and garlic growth; and garlic is generally applied to high nitrogen high potassium per acre after harvesting composite fattening of 15 to 20 kg to prevent premature loss of leaves and promote the transfer of nutrients to garlic. Decision on the specific use of integrated base fertilizer. At the end of the day, garlic, with its weak growth, is resistant to disease. It is intended to strengthen the prevention and control of diseases such as folicosis, rusty disease, as well as greyy disease. Optimus-like formulations such as thionphos-methyl can be used for the treatment of garlic maggots。
Other vegetables. Onions, onions, spinach, etc., are to be cultivated in a timely manner, weeds are to be removed, temperature protection is to be raised and root growth promoted. Water is re-watered in a timely manner according to soil conditions. Vegetables such as onions and spinach are reduced in value by springing, and are collected in a timely manner according to market conditions and growth。
Ii. Reaching the facility enforcement providment answer
(i) fostering quality seedlings. High-quality, high-yield, low-temperature and resistant varieties are selected. Seeds are disinfected before seed is soaked, seed treatment is carried out using hot soup impregnation, pharmaceutical impregnation, dry thermal disinfection, etc. Strengthen seedling management by keeping the temperature in the shed within the appropriate range and keeping the temperature differential at around 10°c, to prevent excessive nighttime temperatures. Prevention of high-wetting of seedbeds and the occurrence of diseases such as root and fall. Some seven days before the discharge, the ventilation cooled, the water was controlled and the cover was gradually removed for low-temperature seedlings。
(ii) conversion management. The solar greenhouses must be cleaned up in time for the early spring, so as to disinfect the sheds and reduce the source base; the arches must have a flexible application of multi-film-cover techniques, which can be established when the minimum temperature in the shed is stabilized at more than 10°c for three consecutive days and at 10°c for the depth of the earth. Increased high-quality organic or high-carbon composting before planting. Vegetables and vegetables are promoted using a high-swidth, wide, 80 to 90 centimetres wide, with a roof of 60 to 70 centimetres wide and a walkway of 90 to 100 centimetres wide. Tomatoes are 20 to 30 cm tall, cucumbers 15 to 25 cm tall, cucumbers are grown on two lines, 40 cm small, tomatoes are 30 to 40 cm wide and cucumbers 20 to 25 cm. When planted, water is poured in, temperature is maintained and root seedlings are promoted。
Iii. Management of open spring vegetable cultivation
In the spring, open vegetables are grown in large areas and in a wide variety of varieties, in accordance with their growth characteristics and weather changes, in due course (settling), and scientific cultivation is managed。
(i) potatoes. Precedence is given to detoxification of primary or primary potato varieties, using high-quality varieties that are adaptive, resilient, productive and commercially good. Sliced blocks 25 to 30 days before seeding. Sliced pedestals are mixed and sprung at 15°c-20°c. Prior to planting, acreage is usually fed with fertilized organic weights of 2,000 to 4,000 kg, with a combination of three dollar (15-10-20) 80 kg and an appropriate amount of fertilizer. Cultivated in single rows (65-70cm) or single rows (80-90cm wide, 30cm long) up to about 25 cm, 20-25 cm long, 10-15 cm deep. The introduction of mechanical seeding was promoted, with one-time work done on the pick-up, seeding, ploughing, covering, etc. In general, 25 days after the broadcast, the seedlings are expected to be released in time to cover 3 to 5 cm of the soil, and to be self-defeating; if the soil is not so tightly covered, they need to be released in time. It is up to the sky to see how the seedlings are watered, with a focus on three times after the seeding, the congealing period and the seal. After the horticultural period, three to five kg per acre of high potassium water solution was applied, usually three times. Integrated agricultural, physical, chemical and other measures to prevent and control diseases such as the plague, etc。
Ginger. When the ginger harvests last year, the fields were wet and the quality of the ginger seed was declining, the emphasis being on the treatment of the ginger seed before planting. (c) the early extraction of a ginger tan, the reduction of the amount of water and the improvement of the temperature of the ginger clot; the selection of the strong ginger seed and the elimination of the thin, soft, water-stained and brownened ginger. During tanning of the ginger seed, appropriate agents are sprayed to prevent pests and pests, and biopharmaceuticals such as hatz mucculinus and dead grassphage are also available. Ginger seed is placed at 80% - 85% air humidity, pre-period temperature of 23°c - 25°c, 20°c - 22°c 10 days later. Soil fumigation can be used for 20 to 30 days before ginger is grown, including chloropicrin, cotton fever, and acres, to mitigate the problem of weighting. Acre application of fully decomposed organic fertilizers of 5,000 to 6,000 kg, high nitrogen high potassium compound fertilizers (16-8-20) of 50 kg and appropriate moderate trace element fat. In the meantime, the sunscreen covers the light. It is desirable to maintain 80-85 per cent water content in the soil during the shrunk season. During the period between late may and the first small-scale earthbreeding, water was poured and per acre was applied to high nitrogen-high potassium water soluble (16-8-20) 2-3kg. In combination with the first small-scale field, 100 kg of organic fertilizer per acre and 25 kg of composite fertilizer (16-8-20) for high nitrogen highs. The second small-scale pyrotechnics (garbages), 25 kg per acre (16-8-20) of high nitrogen-heavy potassium compound fertilizer and 5 kg per acre of micronutrients. When large-breeded soil is used, the commercial organic and high-nitrous potassium compound (16-8-20) 30 kg per acre is applied. Scientific control of pests and diseases such as gingerpest, tubular decomposition and foliage, and damage to hazards。
Iv. Combating all types of agricultural disasters
Precipitation this spring is projected to be between 1 and 2 per cent lower than the same period in the year and slightly higher than the same period in the year. Close attention should be paid to climate change and timely response to disasters such as spring and drought, winter and wind。
(i) response to spring and drought. The soil is rolled deep before the broadcast, the bottom of the ploughs is broken and the soil water is increased. (c) promote membrane cultivation to reduce soil moisture evaporation, giving priority to the use of biodegradable membrane. Be equipped with efficient water-saving equipment such as drip irrigation and micro-jet irrigation。
(ii) to deal with the onset of the spring. The cold flows temporarily, with multiple layers of coverage in the shed, or emergency heating using heat blocks, heaters, etc., to ensure proper temperature. In the field, open vegetables can be protected against cooling by setting wind barriers, planting a plant with plastic sheeting, swirling, etc. Vegetables with mild or cryogenic colds are sprayed with amino acid, potassium phosphate, etc. On the leaves, while the roots combine to apply fertilizers such as curated acid, algae acid, etc., to promote the restoration of plants。
(iii) responding to the wind. Early reinforcement of the greenhouses. The wind comes in a temporary manner, with the early closure of the vents and the proper temperature being kept under pressure, while the membrane line is tightened and the membranes are secured against the wind. In the event of a heavy wind at night, the temperature is secured by an early lid and, if necessary, by two thin wires horizontally and horizontally, to prevent the wind from blowing up. The damage to the facilities and vegetables was checked in time for repair as soon as possible after the storm。
