Matters needing attention in planting fruit and corn

Fruit corn is a kind of super sweet corn suitable for eating raw, with thin skin, juicy, crisp and sweet, which can be eaten directly raw, the thin skin is broken by a bite, the fragrant juice overflows over the teeth and cheeks, and it is very sweet and crisp when eaten raw and cooked, just like fruit, so it is called "fruit corn". There are many varieties of fruit corn, all of which have very high nutritional value. Let's take a look at the notes for growing fruit and corn.

1. Fine soil preparation, timely and phased sowing, harvest and listing one after another. In order to put it on the market early, plastic film mulching or seedling transplanting techniques are advocated to sow seeds early to achieve 3-4 ripening in one year. In order to prolong the harvest time and ensure the market supply, in addition to the scientific matching of early, middle and late maturing varieties, the method of sowing by stages is usually adopted, sowing every 5 or 10 days. The planting area and sowing date should be reasonably determined according to the market demand.

2. reasonable close planting to improve the uniformity of the population. The planting density has a great influence on the yield and quality of sweet corn, and the number of planting plants should depend on the variety and demand. Generally, there are 3500-4000 plants per mu of fresh ears and 500 ~ 6000 plants per mu of fresh ears. The precocious plants were 3500000 plants, and the fresh bamboo shoots were 5500,6000 plants. The density of early-maturing varieties should be higher than that of late-maturing varieties, and the density of the same variety sowing in winter and spring should be slightly higher than that in summer. The emergence rate of sweet corn is low, the seedling potential is weak, and the plant uniformity is poor. Therefore, the actual sowing rate should be twice as much as the suitable panicle number, the balanced growth should be promoted by partial application of seedling fertilizer at 3-4 leaf stage, and the upper limit of suitable density should be set at 5-6 leaf stage. At the same time, according to the characteristics of strong tillering ability of sweet corn, tiller should be removed in time to promote seedling strength.

3. apply fertilizer scientifically and increase the application of phosphorus and potassium. Apply 1000-1500 kg barnyard manure, 20 kg superphosphate and 10 kg potash fertilizer per mu as base fertilizer. 20 kg of urea was applied per mu at seedling stage, 10kg / mu and 10kg / mu at jointing stage, 10kg / mu and 10kg / mu at jointing stage. For those with poor growth, combined with ploughing and soil cultivation, 4-5 kg urea was applied in the silking period. Topdressing should be controlled within 10 to 15 centimeters next to the plant, deep application of holes and combined with ploughing and weeding. Increasing the application of potassium fertilizer can improve the nutritional quality and sugar content of maize, and the application of pure potassium should be 5-10 kg per mu.
