Planting points of waxy corn

(1) Selection of varieties, in addition to paying attention to the high yield and quality traits of the glutinous maize varieties, it is also necessary to pay attention to meet the needs of different consumers, and the varieties should have higher resistance to the main epidemics that have occurred in local corn. .

(II) Arrangement of the production season The seasonal arrangement of planting waxy corn must be considered in combination with factors such as product use:

1. For the purpose of directly picking fresh fruit spikes for market or processing canned foods, we must first predict the market's consumption capacity and the processing capacity of the factory, and scientifically arrange the production season and planting area of ​​waxy corn according to the sales volume and processing volume. Because the harvesting period of waxy corn is very short, generally 22-28 days after pollination, it is necessary to control the harvesting or processing into waxy corn products during the harvesting period. If you want to extend the time to market or processing time, the production should be carried out in stages, with the method of planting early, middle and late varieties. In addition, attention should be paid to the rational use of green stalks to further improve their overall economic benefits.

2. For the purpose of harvesting mature seeds, the production season is arranged in principle the same as ordinary corn.

(3) Isolation of the planting of the glutinous corn gene is a recessive gene mutant of the endosperm trait. When it is crossed with ordinary corn or other corn, the contemporary seed loses its scorpion and becomes ordinary corn, so it must be grown when planting waxy corn. isolation. There are two ways to isolate: one is distance isolation, that is, the field within 200m around it can not grow other types of corn; the second is the time difference isolation, which requires the flowering period to differ by more than 30 days to avoid string powder hybridization.

(4) Seeding density and group control sowing techniques are the same as those of ordinary corn. In general, the suitable density for high yield is 4,500-5,500 plants per mu, the early-maturing varieties are slightly higher, and the late-maturing varieties are slightly lower. The spring sown of the same variety is slightly higher than the summer sown. While grasping the appropriate density, the production potential should be explored by improving the uniformity of the group. Due to the different emergence environments and the problems of the quality of the seeds of waxy corn, the uniformity of emergence is often poor. This difference will increase with the growth process, and there will be large seedlings and seedlings, resulting in empty stalks, spikelets, and high light. Effect group, affecting production. Therefore, efforts should be made to improve the quality of sowing, so that the number of seedlings is 2-3 times that of the appropriate number of panicles; the 3-4 leaves are balanced according to the seedlings; the 5-6 leaves are weakened, and the upper limit of the seedlings to the appropriate density is determined; At the same time, aiming at the characteristics of strong tillering of waxy corn, timely snoring promotes the formation of strong seedlings.

(5) For the waxy corn that is fertilized in spring, the amount of fertilizer applied is about N2.24kg, P2O50.85kg and K2O1.61kg for every 100kg of grain produced. Therefore, the type and amount of fertilizer should be determined according to the target yield. The fertilization method is the same as that of ordinary corn.

(VI) Water management and pest control The water requirement of waxy corn is similar to that of common corn. Attention to anti-staining in the seedling stage, pay attention to drought prevention in the middle and late stages. Compared with ordinary corn, the control of pests and diseases of waxy corn has special requirements. The pests of waxy corn are mainly underground pests at the seedling stage and corn borers at the earing stage. For these situations, the following measures can be taken:

1. When planting, phoxim or 2000-3000 times Lego fruit solution can be used for seed dressing to control the damage of underground pests such as cockroaches, crickets and tigers.

2. For the production of glutinous corn for the purpose of picking fresh corn, it is best to use the method of biological control to control corn mash, that is, to inoculate Trichogramma eggs in the big bell period to control the occurrence and harm of corn mash. If chemical pesticides must be used to control corn borer, low-level pesticides should be used. In the small bell mouth period, the dosage should be as small as possible, that is, use with caution, use less, and use pesticides early, and control the underground pests scientifically and effectively. Pesticide residues are not left on the ear of the milky stage to produce a pollution-free waxy corn product.

3. For the waxy corn that harvests the grain, the control of corn mash can be filled in the big bell mouth period, and the dosage is 1kg of 1% furan granules per acre. The prevention and treatment of diseases is mainly solved by disease-resistant varieties. The control of grass damage is mainly carried out by combining topdressing and cultivating.

(7) Timely harvesting of waxy corn for the purpose of picking fresh corn should be harvested in time after the ripening of the milk; for the waxy corn harvesting the grain, it has the same requirements as the harvest of ordinary corn, that is, when the black powder layer appears in the grain.
