With the continuous development of the market economy and the continuous improvement of the people’s living standards, sweet and waxy corn, mainly fresh food, are increasingly favored and welcomed by farmers. The economic benefits of planting special maize are 2-3 times higher than those of ordinary corn, and the benefits are very considerable. Many farmers have consulted the seed station about their cultivation techniques for growing sweet and waxy corn. According to the problems found in the cultivation of sweet and waxy corn, the author talked about how to plant sweet and waxy corn, and talked about cultivation points and precautions. 1. Isolation and planting of sweet and waxy corn is controlled by a single recessive gene. During the production process, it is necessary to control the purity. Once it is polluted by other pollen, it will seriously affect its flavor and quality. Space isolation and time isolation are used for planting. Space isolation generally requires no other types of corn within a range of 300 m or more, so that pollen outside the isolation zone cannot be invaded and the isolation method is the safest. Time segregation is to advance or delay the sowing time of the corn in the isolation zone so that it is staggered with the corn flowering period outside the isolation zone. Spring sowing can be separated by 30 days, summer sowing interval is 20 days, sowing is too late and the rate of spike formation is low, which seriously affects the yield. 2. Pay attention to site selection and site preparation. Timely sowing of sweet and waxy corn is mainly to harvest fresh and tender ears. Necessities for plant growth are neat and consistent. The time for pollination and pollination is concentrated and the size of the ear is mature and consistent. It is better to choose land that can be dredged and watered, and that can be drained above moderate fertility. Site preparation directly affects the field uniformity of sweet and waxy corn. The spring sowing plots pay attention to the protection of the earth after thawing, so as to create a deep, loose, fine, uniform, fat and wet soil environment. In the early spring ridge habit area, with ridges per 667 square meters to apply high-quality fertilizer 4000kg, 10kg of DAP, 50kg of superphosphate and appropriate amount of potash, so that nitrogen, phosphorus, potassium, organic and inorganic fertilizers used in conjunction. Early harvesting and early harvesting are effective measures to improve the competitiveness of the sweet corn market, and the earlier the listing, the higher the benefits. According to the germination temperature of corn, it is required that the temperature is stable at more than 13°C to germinate normally, and the method of mulching with small sheds can be used to sow 10-15 d earlier. At the same time, the harvesting and processing capacity must be considered, and sowing should be carried out in stages so as to be listed and processed. Generally every 10d broadcast a period. From the production practice, to determine the planting density of sweet waxy corn, we should first consider its commodity traits. Because fresh corn is ear-marked, yield traits are secondary. When the density is too high, the ear tends to become smaller, the weight becomes lighter, the effective ear is reduced, and the commercial value is greatly reduced. Generally 667 square meters Liumiao 3000-3500 strain is appropriate, and the single plant is good. There are many varieties of sweet waxy corn. In order to achieve the batch market, the selection should be suitable for early, middle and late selection. Sweet corn should be preferred to Superman 2000 selected by the Chinese Academy of Agricultural Sciences. Waxy corn and early maturing varieties can be selected as Wanjian No.2 and Wansui No.3, middle and late cooked varieties can be selected from Zhongwan No.1, Zhongwan No.2, and Damin No.10. Pay attention to the introduction of varieties and follow the instructions for planting. 3. Doing well in field management Seedling pests are mainly small tigers and earthworms, and 18% Kefu or 20% formazan and corn special seed coating agents can be used for seed dressing. Usually 4-5 leaves between the seedlings, 6-7 leaves Dingmiao. In combination with Dingmiao, it is necessary to remove yellow and white seedlings and disease, weak seedlings, and leave seedlings of the same size. Timely cultivating and weeding, combined with cultivating and weeding suitable soil. Sweet glutinous corn is more likely to produce tillers than normal corn, and it is necessary to remove the tillers in time to avoid the consumption of water and nutrients by the tillers and affect the ventilation and light transmission in the fields. Because of the unique flavor of sweet waxy corn, the pollination and silking period is extremely vulnerable to pests such as big black beetles, and it is necessary to go to the field and catch it manually every day. At this point can not use insecticides. Sweet glutinous corn mainly pay attention to flavor, taste, mainly fresh food. If fertilizer and water are not properly managed, the flavor will be poor and the product value will be reduced. Watering once in 10 days before harvest can improve the quality and extend the harvesting period. 4, timely harvest timely harvest is a key link to ensure the quality of the product. Because the taste changes with the growth process of the grain. The best taste period is the most suitable harvest period. Earlier, the grain has too much water content, too little dry matter, tasteless, bad taste, low yield, and should not be preserved. At the end of the day, the sugar in the grain was converted into starch, the seed coat was thickened, and the taste was not good and the flavor was reduced. Appropriate harvesting period should be judged by its own characteristics, planting areas, uses, and climate characteristics at that time. According to the number of days after pollination and grain moisture content, sugar content, combined flavor, taste to determine sweet corn, the most suitable harvest period is about 23-25 ​​days after pollination, when the water content is about 62%, it tastes sweet and delicious. , The best flavor and taste. Sweet glutinous corn fresh ear is difficult to keep fresh, and its quality will change with time after harvest. It should be processed as soon as possible in the morning and after harvest, processing must be finished within 10 hours. At the same time, the volume of recovery is determined by sales and processing capacity. If harvested ears cannot be sold and processed in time, they should be stored at the lowest possible temperature.
