The town of changnan is located in the eastern part of fujian yongan city, with 950 hm2 of arable land, with a total population of 23,759, and a total area of 12,478 hm2 under its jurisdiction, fertile soil, deep soil, good drainage and irrigation conditions and well-developed agricultural infrastructure. Sweet corn, also known as vegetable corn, is of high nutritional value, has a large number of processed products, combines economic benefits, market potential, development prospects and production cycles. In recent years, the smoke-cooking pattern has been growing sweet corn at the end of the baked smoke in the village of khunnan, the capital village, which has been growing on an early scale and with good economic benefits, with a steady annual area of 200 hm2,667 m2 maize production of 1,250-1500 kg. High-yielding cultivation techniques for sugar corn are summarized below。
1 land selection
(b) select plots with a deep layer of soil, fertile soil, good permeability, moderate alkalinity, ease of discharge, easier transport and adequate light. The area below 700 m above sea level is better served by the cultivation of uncontaminated fields in the area。
2. Varieties selection
The choice of good sweet maize varieties is key to the high yield of post-smoking sweet corn models. There is a general choice of hybrid varieties that are good, productive, resilient and adaptable. Sugar corn is grown after smoke, and late cold weather affects sweet maize pollination. Local climatic conditions, soil conditions and market demand should therefore be fully taken into account in the selection of sweet maize varieties. In the case of fruit and vegetables, which are mainly made out of young fruit and vegetables, the varieties of super-sweet corn shall be chosen; in the case of cannery, the varieties of ordinary sweet corn shall be chosen, and the suitable varieties shall be chosen according to the size and quality of the fruit and vegetables required by the manufacturer. In production, care is taken to combine early, medium- and late-literate varieties and to continuously provide raw products to markets and processing plants. In recent years, the town of changnan has chosen more than 981 sugars, 5 summers and 3 summers。
3 implementation of segregated cultivation
The cultivation of sweet and smoked maize requires strict segregation, mostly in space and time. Space segregation: in the fields where sweet maize is grown, it is not possible to grow the same type of sweet corn within 300 m at the same time; in the same time it is not possible to grow ordinary or other types of sweet corn that bloom during the same period. Natural barriers, such as houses, trees, mountain posts, etc., can appropriately reduce isolation distances, and if spatial isolation is not possible, staggered planting periods can be used to avoid the flowering of different varieties over time。
4 period determined
In mid-june, we ended in mid-june, with three to four pieces of tobacco. The premature planting of sweet maize with roasted smokes tends to create seedlings; the late planting of sweet corn and the exposure of the masculinity period to the cold of the autumn lead to poor conditions that affect product yields and quality。
5 the way sweet corn is grown
Live broadcasts of 667 m2 are conducted live, using a range of 0. 4 to 0. 5 kg, with one line of maize per roasted cigarette, 15 to 20 cm, two grains per den, two to three cm thick and single seedlings. The seedlings are grown in nutrients or small arches, and are grown in soil between the two and three centrifugal periods, keeping the seedlings from having direct contact with the base fat, with one plant in each den from 15 to 20 cm。
6 field management
After the roasted smoke harvest, shovels are used to avoid touching maize plantations and to clear the smoke and weeds from the smoke。
2 seedlings, solid seedlings 3 to 5 leaf periods, the removal of weak seedlings, sick seedlings, small seedlings and bad seedlings, each of which leaves a strong seedling in each of the dens, and if there is a shortage of seedlings, it is filled with strong seedlings in a timely manner. 7-leaf seedlings, 667 m2 guaranteed basic seedlings of 3,500 to 4,000。
3. The principle of front-, mid- and back-to-back fertilization of sweet corn, the one-time application of phosphorus fertiliser as a base, and 667 m2spp through calcium phosphate 75 to 100 kg. Early pursuit of fertilisation, early application and re-application of estuarine fertilizer, ensuring that sweet maize plantations grow “green by the way”, followed by fertilisation of 667 m2 by applying imported compound fertilizers of 100 to 150 kg, during seeding periods of 5 to 10 kg, and during throttle periods of 40 to 65 kg. In each case, the fertilizer is applied as deep as possible and should be combined with pine soil, earthbreeding, guttering and weeding。
4 water management 4 during the period of seedlings, soil is kept wet in the field to avoid over-drying, soil is dry enough to fill the water with appropriate quantities, and water is drained at speed, with a view to filling shallow trenches, and low-lying plots should pay special attention to draining open trenches and waterproofing。
In time, male defecation should take place when the male has just been pumped out and has not been pollinating, so it will be better at 9-1-6 p. M. Because of the high temperatures, the low water content of the plant, and the susceptibility of the wounds to healing and the prevention of bacterial infections. Should be separated or separated. In order to produce high-quality fruit, with a high success rate, it is necessary to remove the surplus, i. E., to retain only the largest one and, in principle, one。
6 pest and pest management (ppm) prohibits the use of highly toxic, highly residual or “triple”-acting agents during the whole reproductive period to ensure the quality and safety of the cyanide. Sweet corn is mainly ailment, scabs, small scabs, rusty, and the pests are mainly tigers. In the early stages of this disease, 500 times the liquids of the 5 per cent acinogen, 50 per cent of the degenerative special wwable powder, 50 per cent of the more than ferocious powder, 700 times the liquids, sprayed the leaves on the face of the leaves, the back of the leaves, and below the ears of the fruit; in the early stages of the large and small spectropathy, the spray of 600 to 800 times the humid powder was even; in the early stages of the rustic disease, 25 per cent of the filamentary powders (triazone) were sprayed with 2,000 to 3,000 times the liquid powder, 10 to 15 d 1 and two to three times in a row, and the powdered antiquant was effective for a long period, so that the growth of the penis, the leaf and the sprouts was inhibited, so that the concentration could not increase arbitrarily and the fruit was cut by 20 d before the harvest. Tigers can use 2. 5% of the enemy to kill (bromocypermethrin) or 2. 5% of the proposed pyrethroid formulations, such as emulsifiable emulsion (high-efficiency chlorocypermethrin), at seeding or before seeding, to water at 1600 hours。
7. Timely collection
Sweet maize, which is mainly ingested with green fruit, has a significant impact on the quality of its commodities and nutrition during harvest time, with early harvests, low seed content, and too late harvests, which results in rigidity and loss of unique flavors. After pollination, 18-23 d is used to squeeze the upper seed in the ear of the fruit with the finger, and the fluid from which it flows is the milk for the appropriate harvest period. Each harvest shall take place at low temperatures in the morning and be sold on time。
This is all of today's content, and growers can refer more to it, or they can comment on what they want to know about the three agricultural techniques, and they can make it easier for them to do so. It's not easy to create, and i'd like you to look at the writer and forward the positive comments. Thank you
