If you want to cultivate high-quality waxy corn, you can use the following cultivation techniques.
1. Quality characteristics of waxy corn
Corn eaten or processed with tender ears is called fresh corn, also known as vegetable corn, fruit and vegetable corn. The most current fresh corn is glutinous corn. The plant is robust, the ears are beautiful, firm and full, the commodity is good, the crystal is bright and translucent after cooking, the taste is delicate, sweet, sticky and fragrant, suitable for fresh food, quick freezing, vacuum packaging, and the harvesting period is longer, and it is not easy to deteriorate after harvesting. . Because of the hidden genes in the waxy corn, the starch in the corn endosperm has high viscosity, good palatability, high expansion rate, water absorption and transparency. In addition to fresh food, it can also be used as high-quality feed and advanced industry. Raw materials (thickeners, binders, stabilizers, sizing agents), etc.
2. Development prospects
2.1 The consumer market is large, and consumption is increasing year by year.
The excellent taste of glutinous corn and its rich nutrition (high in protein and lysine content compared with common corn) are beneficial to improve the dietary structure of residents. Xiling District is Xushen Cemetery, Shaying Park, Medical College, Shuanghui and Dongcheng. The industrial agglomeration area and other gathering places have great market potential.
2.2 The needs of animal husbandry development
After the corn is harvested, its stems and leaves are green and juicy, rich in nutrients, and it is a good feed for cattle and sheep. Waxy corn stalks can be supplied to nearby dairy farms.
3. Cultivation techniques
3.1 Plot selection
Choose soil fertile, convenient irrigation and drainage, clean water, no pollution, certain isolation conditions, and convenient transportation, create deep, loose, fine, uniform, fat and wet soil environment for seedlings, ensure seedlings, seedlings, and seedlings Even and strong.
3.2 Variety selection
When selecting a variety, it is necessary to introduce the test according to the needs of the local market and then scale the production. At present, the quality of the white waxy corn is the best, and some yellow waxy corn is also good, while the black, purple, red, and colored varieties are relatively poor in quality.
3.3 Isolation planting to prevent skein
The waxy corn enamel is controlled by recessive genes and has a pollen sensation. If other types of corn pollen fall on the filament, the grain will lose its enamel and become ordinary corn. Therefore, the cultivation of waxy corn must be isolated. 1 Space isolation requires that other types of corn varieties cannot be planted within the range of more than 300 meters to prevent stalking. 2 Time isolation is to advance or postpone the sowing time of waxy corn, and the flowering period is wrong. Generally, the spring sowing interval is more than 30 days, and the summer sowing interval is more than 20 days. 3 Obstruction is isolated by natural barriers such as trees, hills, villages, etc., generally above 150 meters, and at least not less than 60 meters.
3.4 Staged sowing, rational close planting
Seeding is started when the ground temperature of 5 to 10 cm reaches 10 to 12 °C. In order to prevent excessive concentration or lack of manpower, it can be planted in stages, listed in batches, planted once every 7 to 10 days, and broadcasted for 2 to 3 periods. The live broadcast of the glutinous corn field in Zhaoling District is usually in the middle of April, and at the latest in mid-July. If the fresh ear is listed, it is appropriate to plant 3,500 to 4,000 plants on 667 square meters. If the fruit is vacuum packed, it is appropriate to plant 4,000 to 4,000 square meters of 667 square meters.
3.5 Field Management
The amount of fertilizer required for waxy corn is higher than that of common corn. It is necessary to apply organic fertilizer, NPK fertilizer; it should be protected from drought during flowering, and should be watered in the middle of filling. The glutinous corn has more tillers and should be removed in time during the jointing stage; one multi-ear is often found in the heading stage, and only the uppermost ear is generally retained, and the rest is removed in time. Due to the high planting density, the leaves are shaded, which may lead to poor pollination, baldness and lack of grain. It should be selected from sunny day and no wind in the full bloom period from 9:00 to 11:00, using the shaker method or the drawstring method. Artificial pollination, usually once every other day, takes 3 to 4 times.
3.6 Pest Control
Pests and diseases mainly include silk smut, ground tiger, corn borer, etc., should adhere to the "prevention-oriented, comprehensive prevention" plant protection policy, try to use, use less, use chemical pesticides as much as possible, prohibit the use of high-level, high-residue pesticides, the most It is good to use pyrethroid pesticides, and it is forbidden to use pesticides 15 days before harvesting.
3.7 Harvest at the right time
The harvest is too early and too tender, and the fragrance is not enough; too late, the grain hardens, and the sweetness is lacking. It should be harvested 25 to 30 days after pollination, preferably within 1 to 2 days to ensure the best taste of waxy corn.
The above is the cultivation technology of waxy corn, for your reference, and hope to help you. Huinong School has more relevant agricultural technology knowledge. Continue to pay attention to Huinong School to answer questions during planting or breeding.
