The difference between ordinary corn and ball shape popcorn to make popcorn
We often go to the cinema to watch movies. It is the most common thing to choose to buy a bucket of popcorn. We all know that popcorn is made from corn, but this type of corn is different from ordinary corn. The same, so I am also interested in this kind of corn that can be made into spherical popcorn. What is the difference between ordinary corn and spherical popcorn?
(1) Variety selection
According to the length of the local frost-free period, select varieties with high yield, good popcorn quality, and moderate growth period. There are three popular popcorn kernels on the market: white rice type, yellow large pearl type and yellow small pearl type. A suitable popcorn variety requires high lodging resistance and disease resistance when selecting it, so that its high-yield and high-quality performance can be brought into full play in production.
(2) Site selection and isolation
Popcorn has strict requirements on the soil. It should be planted on plots with medium soil fertility and above, not prone to drought, not prone to waterlogging, and no saline alkali. The popping performance of popcorn is a trait controlled by recessive polygenes, and it has a certain impact on the popping effect after hybridization with normal corn. Therefore, the raw material production field should be separated from the normal corn field by more than 200 meters.
(3) Reasonable fertilization
Popcorn grows slowly at the seedling stage, so the application of base fertilizer should be paid attention to. Mainly farmyard manure, 3000~4000 kg farmyard manure per mu. For plots with a soil organic matter of about 1.5%, apply 10-15 kg of diammonium phosphate or 10 kg of ammonium sulfate plus 30 kg of superphosphate with the seed when planting, and avoid direct contact with the seeds to affect the germination of the seeds. In the sowing line between the acupoints. Topdressing nitrogen fertilizer in the big bell mouth period, apply 20-25 kg urea or 45-55 kg ammonium sulfate. In recent years, some plots have been applying chemical fertilizers for a long time, and the soil is severely lacking in potassium, which affects the normal development of plants, especially the leaves are withered and yellow at the seedling stage, and the growth is slow. The reaction of popcorn to potassium is more sensitive than that of ordinary corn, so sufficient potassium fertilizer should be applied, generally 10~15 kg potassium sulfate per mu.
(4) Sowing in time
All corresponding technologies that are suitable for improving the sowing quality of ordinary corn are suitable for the sowing of popcorn. Because of its small grains and weak soil arching force, high seeding quality is required. When sowing, cover the soil with 3~4 cm, and generally adopt equidistant on-demand sowing by opening the furrow on the ridge, sowing 3 seeds per hole, and fertilizing in strips or holes. Popcorn generally develops fast tassels, slow development of female ears, and tight bracts. Sowing in stages is conducive to pollination and prevents baldness. Generally, the seeds are planted in alternate rows first, and then planted in empty rows after 5 days.
(5) Reasonable dense planting
According to the planting method, soil fertility and variety, different densities are adopted. The growth period of most popcorn corn is 120 to 125 days. Popcorn has a smaller plant than ordinary corn and has lower productivity per plant. Therefore, the planting density is 10% to 20% higher than that of local ordinary corn, with 4000 to 5000 plants per mu. Too sparse, insufficient number of plants will result in reduced yield, and too dense will result in small ears and empty stalks. What needs to be emphasized is that popcorn is not allowed to fill seedlings and seedlings in the field to prevent the emergence of three types of seedlings. Because the maturity of the three types of seedlings is inconsistent with the normal seedlings, their quality will be reduced, and the popping rate and expansion coefficient will be affected.
