Where is the planting technology of sticky corn?

What's the difference between sticky corn and normal corn? Where is the planting technology of sticky corn? Also asked the netizens who have planted to help introduce the so-called sticky corn, which is rich in sticky corn. Generally, sticky corn grains have a thicker waxy endosperm, which is more like the glossy glassy (transparent) grains of hard corn and horse-toothed corn. Its chemical and physical properties are controlled by a single recessive gene (wx), which is located on chromosome 9. 100% of the starch in the endosperm is amylopectin. In addition to being used as vegetable corn for human fresh food, this kind of corn can be used as livestock feed to improve feeding efficiency. It also has industrial uses. There is waxy, commonly known as sticky. The nutritional content of sticky corn is higher than that of ordinary corn, containing 7075% starch, more than 10% protein, 40.5% fat, 2% multivitamins, more protein than rice, and the highest contents of fat and VB2. Yellow corn also contains vitamin A (carotene) that is deficient in rice and wheat. The genetic function of sticky corn wx gene is to change the type and properties of sticky corn endosperm starch. The molecular weight of sticky corn starch is more than 10 times lower than that of common corn, and its edible digestion is more than 20% higher than that of common corn. The value of sticky corn is much higher than that of ordinary corn, so the planting technology of sticky corn has been sorted out by the farming network, which is listed in detail below for netizens' reference. First, the selection of sticky corn planting land to sort out: the planting of sticky corn should choose the land with irrigation conditions with flat terrain and medium fertility. And in order to maintain the seed character of sticky corn, prevent the self-inductive effect of pollen, reduce the viscosity and affect the appearance, it must be isolated from other types of corn. General spatial isolation can not be less than 300 meters, barrier isolation can not be less than 150 meters; time isolation is a 30-day difference between sowing time and other corn. 2. Fertilization of sticky corn: it is best to apply 2000 kg of high-quality farm manure per mu of sticky corn, or 30 kg of diammonium fertilizer, 10 kg of potassium sulfate and 1.5 kg of zinc sulfate with a depth of 10-15 cm during soil preparation. Sow before sowing to prevent burning buds from affecting seedling emergence. Because sticky corn is a fresh food, early topdressing and irrigation is very important to obtain high quality and high yield. The first topdressing was carried out at 7-9 leaves, and 15 kg urea was applied per mu. For the second time, 30kg urea was applied at the jointing stage. Third, the sowing of sticky corn: the amount of seeds used per mu of sticky corn is 2 kg. Soaking and accelerating germination should be carried out before sowing. The suitable temperature for accelerating germination is 25 ℃ and direct seeding after the seeds are exposed. The most suitable sowing time of sticky corn is from April 25th to May 5th. When the soil temperature is 5 cm and 8 ℃, the sticky corn can be sown with 3500 grains per mu and 3 grains per hole. Because the grain of sticky corn is not full, the content of starch and other nutrients is low, the germination potential is weak, and the ability of top soil of young buds is poor, the emergence rate of sticky corn is much lower than that of ordinary corn. Sowing should not be too deep, appropriate shallow sowing, shallow cover soil, generally cover soil about 2-4 cm. In order to meet the market demand, in case of out-of-date harvest, quality decline, falling prices affect economic income, so sowing by stages and listing in batches. The live broadcast can be broadcast in stages from April 25 to June 10, every 5-7 days. Generally, due to the low temperature in the first two periods, the staggering time can be appropriately extended. The temperature of the grain filling maturity period sown in June is lower, the grain filling speed of corn is slow, and the two periods can be shorter. The methods of plastic film mulching, paper tube seedling raising and plastic plate seedling transplanting can be used for early listing. It can be sown 7-10 days in advance and transplant with 3 leaves in one heart. The principle is to stagger the frost period after emergence or planting. If the seedlings are raised in the greenhouse and then transplanted into the plastic greenhouse, the seeds can be sown at the beginning of April, and the early sticky corn varieties can also be replanted with wheat and Chinese cabbage to raise seedlings 10-15 days before wheat harvest. Fourth, the management method of sticky corn ploughing: 50% Acetochlor EC 75ml / mu can be used for weeding in corn field, and the amount of liquid sprayed per mu is at least 30kg, sprayed before seedling after sowing. Those who still plant corn in the next crop can also add atrazine to kill weeds when irrigating water, with a dosage of 1 kg per mu. Sticky corn in the seedling stage should ensure that the seedling is complete, uniform, uniform and strong. The seedlings were determined early in the three-leaf stage, leaving 1 plant in each hole, applying 5kg urea per mu after fixing the seedlings, spraying once to control aphids and armyworm, thrips and so on, using 1500 times of 40% dimethoate emulsion. Because sticky corn is prone to tillering, it is found that the girl should be removed, and the sooner it is broken, the better, otherwise it consumes oxygen and affects the commercialization of spikes and ears. In case of abnormal years, it is easy to have many spikes, so it is best to leave only 1 or 2 ears above. For those who sell green ears, it is best to keep the upper ear, with 6-8 leaves at the node position, so that the stick is big and the grain is full and easy to sell. In the sticky corn jointing stage, 30 kg per mu of fertilizer is applied, mainly to prevent "sticking neck drought" to ensure water supply. When the relative water holding capacity in the field is less than 70%, water should be irrigated for 1 to 2 times. Because corn borer is more important to fresh corn than grain corn. Because the insect eats the ear completely loses the commodity value, but the grain corn only reduces the yield. The heart was perfused with 3% carbofuran granules or 2.5% zinc sulfuric acid granules. When the filaments of the female ear are spit out, artificial pollination can be assisted. Fifth, timely harvest: because the green food sticky corn is sticky and fragrant at the end of milk ripening, the quality is good, the palatability is the best, and it is the best harvest time. Pay attention to the early morning harvest before listing, so as to avoid collapse and bad appearance and color. How to choose and purchase Maize Seeds and how to accelerate germination
