Embodiment Construction

[0013] The invention discloses a method for adding rice husk ash to improve acidic soil for planting sweet corn, which mainly includes:

[0014] (1) Reasonable soil preparation: two weeks before the sowing of sweet corn, soil preparation should be carried out. When preparing the land, 2500-3000 kg of rice husk ash should be evenly applied per mu, and then turned and mixed with a rotary tiller; Land 1 time, planting sweet corn on-demand in autumn;

[0015] (2) Variety selection: It is better to choose a sweet corn variety with a growth period of about 90 days, which is conducive to avoiding the high temperature and drought in the middle and late July;

[0016] (3) Sowing time: In southern subtropical regions, spring sweet corn is sown on April 1-10 and harvested on July 1-10. Autumn sweet corn is sown on August 1-15 and harvested in early November. Seedlings can be raised and transplanted 15-30 days in advance;

[0017] (4) Planting density: Sweet corn is planted in wide and ...

Abstract

The invention provides a sweet corn planting method for acid rain region in the south, primarily comprising the steps of adding an appropriate amount of rice husk ash, performing land preparation moderately, selecting time for sowing, controlling planting density, optimizing nitrogenous fertilizer management, and harvesting. With applying of the rice husk ash and reducing of chemical nitrogenous fertilizer, adverse impact of acid rain can be relieved, and soil nutrient is improved. The sweet corn planting method has the advantages of slowing down soil acidification of the acid rain region in the south, reducing application of nitrogenous fertilizer, saving production cost, and maintaining yield and quality of sweet corn to meet customers' demands.

Description

technical field [0001] The invention belongs to the technical field of crop planting, in particular to a sweet corn planting method for slowing acid rain and acidifying soil. Background technique [0002] Judging from the data of environmental monitoring stations in recent years, acid rain areas in central China, represented by Changsha, Ganzhou, Nanchang, and Huaihua, have become one of the most severely polluted areas in the country. Acid rain will lead to soil acidification, affect the behavior of chemical elements in the soil and disrupt its balance, resulting in the loss of organic matter and the decrease of nitrogen and phosphorus content, seriously affecting soil quality, and then affecting crop yield and quality. Taking effective measures to slow down soil acidification is very important to protect soil quality and maintain crop production in acid rain areas. At present, the common method of improving soil acidity is to apply lime, but long-term or large-scale appli...
