Fresh corn cultivation techniques in winter
1. The choice of the planting zone is that the average annual temperature is above 18°C, and the average monthly temperature in January is >7°C. There are few frost-free or frost-free transport facilities and there are low-hot valley areas with irrigation conditions. 2. The choice of planting plots and the preparation before planting are based on the flat land with fertile soil and convenient drainage and irrigation. For every 667 watts of organic fertilizer used, 1500 mash and compound fertilizer 30 ounces were mixed and mixed into the planting ditch or planting pond as base fertilizer. 3. Cultivation techniques 3.1 Isolation Planting Choose good varieties to be planted together. Do not sow other types of corn around the same time so as not to affect the quality after stringing. Planting with other corn varieties in the wrong period is generally more than 30 days, and the space isolation distance can not be less than 500m. If there are natural barriers such as forests and tall buildings, the isolation distance can be appropriately shortened. 3.2 Variety selection is mainly based on early maturing or medium maturing type 3.3 sowing time from November to December sowing, harvested from March to April. When sowing, the land must be flat and thin, and be deep, loose, fine, and uniform. The thickness of the cover should be 2-3%, and the thickness of the cover should be avoided. In particular, sweet and crisp corn seed with weak top soil capacity. The planting density is 3600-3800 strains and 667 tons. Covering with plastic film to raise the temperature, and strive to mention the morning market. 3.4 Prevention and Control of Underground Pests Before sowing, 3% green land insects and organic fertilizers are mixed or separately spread in planting trenches or planting ponds (with a dosage of 2??667?) to prevent and control underground pests. 3.5 Field management is the same as other winter corn management except that there is a slight difference in fertilization. Since the temperature of fresh corn in winter is gradually reduced after sowing, the corn grows more slowly after emergence and even grows for a period of time. The water absorption capacity of the roots is weak, and the amount of fertilizer needed is also small. In the second year, the temperature gradually rises, and the plants are also transferred. The water requirement for vegetative growth and reproductive growth is during the period of supervision of the demand for fertilizers, the growth rate is fast, and the water absorption capacity of the root system is strong. Therefore, according to the growth characteristics of winter fresh corn, the fertilizer is applied to the base fertilizer, early application, and light application. Apply Miao Fei, cultivate strong seedlings, skillfully apply stalk fertilizer, apply panicle fertilizer, and do not apply granule fertilizer. The main types of fertilizers are organic fertilizers, supplemented by chemical fertilizers, combined with nitrogen, phosphorus and potassium, and zinc fertilizers. 4. Harvesting. Harvested corn is harvested with fresh fruit. Therefore, about 25 days after pollination, the loquat leaf is torn to check the ear maturity and timely harvested and marketed. It is usually listed on the day of harvest to keep the ear fresh.
