Embodiment Construction

[0010] The present invention will be further described below in conjunction with embodiment.

[0011] 1. Seeds and their treatment

[0012] (1) Variety selection: According to the ecological conditions, select the sweet and glutinous varieties with good quality, strong stress resistance and high yield that have been approved and promoted. Zhongnuo 304 and Nongda Chaotian No. 1 varieties were used.

[0013] (2) Seed quality: The purity and clarity of the seeds should not be lower than 98%, the germination rate should not be lower than 90%, and the water content should not be higher than 16%.

[0014] (3) Seed treatment: 15 days before sowing, dry the seeds for 2-3 days; 10 days before sowing, carry out 1-2 germination tests; before sowing, soak the seeds in water for 8-12 hours, then remove them and place them in 20- Germination is carried out at room temperature of 25 degrees, turned every 2-3 hours, and after the radicle is exposed from the seeds, put them in a cool place t...

Abstract

The invention relates to the technical field of agriculture, which is a cultivating method for prolonging the picking time of fresh ears of sweet and waxy corns, applies a method of overall planning integration, and constructs a comprehensive cultivating technical system which takes warming, staging, and assortment-matching as main bodies. Premature breeds are adopted to grow seedlings which are grown by film mulching, and fresh ears are picked 20 days beforehand. Seedlings are scientifically planted by stages (3-4 stages), and fresh ears are deferred for 30 days to pick. Early, middle and lately mature breeds are matched and planted, and 30 days are prolonged to pick up fresh ears. The invention assures breeds according to the climate environment and market requirements, assures planting period numbers according to the biological performance of breeds, and assures warming planting styles according to the operating and manufacturing strength, and organically combines warming, staging, and the breeds-matching technique through overall consideration and optimum assembly. The invention effectively utilizes light, water and heat resources, improves manufacturing performance, and realizes double efficiency-increasing of planting and processing, and the continuous picking of fresh ears reaches 80 days.

Description

technical field [0001] The invention relates to a cultivation method for crops, more specifically, the invention relates to a cultivation method for prolonging the harvest period of fresh ear of sweet and waxy corn. Background technique [0002] The biological characteristics of sweet and waxy corn are the same as common corn, that is, they are all C4 crops, with tall plants, luxuriant leaves, high photosynthetic efficiency and high biological yield. The difference from ordinary corn, that is, its superiority, is that sweet corn has a higher sugar content and has a sweet feeling; waxy corn has a high amylopectin content and is sticky. The food made from these two kinds of corn has special flavor and good taste, and is very popular among people. [0003] With the development of society, the advancement of science and the improvement of people's cultural and material living standards, the production of sweet and waxy corn has developed rapidly. At present, the United States ...
