Embodiment Construction

[0015] The high-yield corn planting method of the present invention includes the following steps.

[0016] (1) Isolated planting, sowing in stages Due to the hybridization of sweet and waxy corn with common corn string flour, the grains are easy to become common corn, losing sweetness and waxiness. Therefore, the planting of sweet and waxy corn should be isolated from common corn, which can be separated by time and space. In order to obtain better economic value, facility cultivation techniques such as plastic film mulching, transplanting of seedlings, transplanting of milk seedlings in trays and even greenhouse cultivation can be adopted, and sowing in batches and stages every 5-7 days. Generally, 45 kg of nitrogen, phosphorus and potassium compound fertilizer and 1 kg of zinc sulfate fertilizer are used as base fertilizer per mu. Take the planting method of large and small rows, the large row spacing is 80-90 cm, the small row spacing is 50-60 cm, the plant spacing depends ...

Abstract

A high-yield corn planting method belongs to the field of agriculture; forestry; animal husbandry; hunting; trapping; fishing technology, and particularly relates to a corn planting method. The invention provides a high-yield corn planting method with high yield, green and pollution-free. The high-yield corn planting method comprises the following steps. (1) Isolated planting, staged sowing due to the hybridization of sweet and waxy corn with common corn flour, the grains are easy to become common corn. (2) Seed preparation, selection of excellent hybrids: Excellent hybrids have good potential for increasing yield and are the basis for high yield of corn. The appropriate varieties should be selected in combination with the ecological types of various places. (4) Plowing and land preparation, the plowing depth should be 18cm. For high soil fertility, thick plowing layer, large amount of basal application, plowing depth can reach 20cm; otherwise, it should be shallow. (5) The sowing depth is generally 4 to 6 cm. But generally not more than 8cm. It should be noted that too shallow sowing in soil with better soil moisture and fertility will produce a large amount of ineffective tillers at the seedling stage.

Description

technical field [0001] The present invention belongs to agriculture; Forestry; Animal husbandry; Hunting; Background technique [0002] Corn is the largest food crop in China. In the biological scope, corn is a carbon 4 plant, but the bracts use C3 mode for photosynthesis, which is a monoecious plant. The main producing area is located in the third largest corn belt in the world - China's Songliao Plain corn belt. The total planting area of ​​corn is about 1249.35 square kilometers, also known as maize, corn (corn stick), corn, cob, and mallet. The Mufu mountain system in Hubei is called Yulu (because the rhizome looks like a reed, and the fruit has the water head of jade), in Chaoshan dialect it is called Youmeiren (because it was introduced from America), in Cantonese it is called corn, in Hokkien it is called fanmai, Jiangxi It is called "Baoxiu". It is an annual gramineous herbaceous plant, which is an important food crop and an important source of feed. It is rich in...
