Embodiment Construction

[0012] Base fertilizer application: choose 1 mu of sandy soil with fertile soil, convenient irrigation and drainage, and good ventilation, and apply 20 kg of nitrogen fertilizer, 9 kg of phosphorus fertilizer, 4.5 kg of potassium fertilizer, and 0.3 kg of potassium sulfate;

[0013] Sowing: In the field, the ground temperature in the 1-10 cm soil layer is stable above 10 degrees Celsius, and the temperature is stable above 16--17 degrees Celsius, sow with 2 kg of seeds, sowing at a depth of 3 cm, coating or spreading poisonous grain powder to prevent pests, after sowing Appropriate suppression to facilitate seed water absorption and germination.

[0014] Planting: the appropriate density of planting is 4,000 plants, with a row spacing of 2 feet and a plant spacing of 0.8 feet;

[0015] One-time top dressing: 20 kg of nitrogen fertilizer, 9 kg of phosphate fertilizer, 4.5 kg of potassium fertilizer, and 0.3 kg of potassium sulfate from the seedling stage to the trumpet stage; ...

Abstract

A planting method for improving maize yield comprises the steps of applying base fertilizer, seeding, planting, primary topdressing, preventing pests and diseases, secondary topdressing, harvesting and the like. The method is characterized in that a sandy loam land which is fertile in soil, convenient to irrigate and drain and good in ventilation is selected to be sufficiently applied with the base fertilizer. Generally, an acre is applied with 20 kilograms of nitrogenous fertilizer, 9 kilograms of phosphate fertilizer, 4.5 kilograms of potash fertilizer and 0.3 grams of potassium sulfate; seeding is carried out when the air temperature is stabilized above 16-17 DEG C, 1.5-2 kilograms of seeds are seeded in each acre, and the planting density is preferably 4000 plants; the primary topdressing is carried out from a seedling stage to a trumpet stage, and the fertilizer type and fertilizing amount are the same as those of the base fertilizer; medicine is applied timely; when maizes just sprout, the secondary topdressing is carried out, and the fertilizer type and fertilizing amount are the same with those of the primary topdressing; and generally, harvesting can be carried out for 20-28 days after the pollination. The method is used for solving the problems of yellow grow corn cob skins, poor maize quality, low market price and poor benefit of waxy corn planting with once fertilizing, and is suitable for planting various maizes.

Description

technical field [0001] The invention relates to the field of planting crops, in particular to a planting method for improving the yield and quality of corn. Background technique [0002] At present, in the cultivation of waxy corn, people all adopt the traditional method of applying basal fertilizer and one-time topdressing. The disadvantage is that when the corn is harvested, the corn cob skin turns yellow and the quality is poor, the yield of corn is low, the market price is low, and the benefit is poor. Contents of the invention [0003] The present invention aims to solve the problems of corn cob skin yellowing, poor quality, low corn yield, low market price, and poor benefit caused by topdressing fertilizer once in corn planting, and is invented to improve the yield, quality and benefit of waxy corn planting method. [0004] In order to solve the above-mentioned problems, the technical solution adopted by the present invention is a planting method for improving the y...
