Protective garlic cultivation method

Abstract

The invention discloses a protective garlic cultivation method, which includes: preforming no tillage for moisture sides of soil with preceding crop straw clipped, and digging an irrigation and drainage ditch between two moisture sides. Garlic serves as the main crop, broad bean or pea serves as the auxiliary crop, a main crop area is 160cm in breadth, an auxiliary crop area is 40cm in breadth, the two areas are 20cm away from each other, a no-tillage garlic hill-drop planter is used to drill holes for planting garlic, spacing in rows and spacing between rows of garlic are 5cmX5cm, spacing inrows and spacing between rows of the auxiliary crop are 10cmX10cm, organic fertilizer, phosphate fertilizer and nitrogenous fertilizer serve as base fertilizer for the main crop, organic fertilizer and phosphate fertilizer serve as the base fertilizer for the auxiliary crop, the surface of the soil is covered with straws after seeding, and the main crop is topdressed with nitrogenous fertilizer and potash fertilizer. By the method, garlic yield is increased greatly by 15%, microbial activity and organic content of the soil are increased by 15% and 12% respectively, income is increased by 26%,nitrate nitrogen in penetrating water of the soil is reduced by 66%, accumulation of nitrate nitrogen in the soil is reduced by 22%, and loss of total nitrogen is reduced by 77%.

Description

technical field [0001] The invention relates to the technical field of agricultural environmental protection, in particular to a protective cultivation method for garlic. Background technique [0002] The garlic of prior art ( A. saticum L.) The production method is unsustainable. It will cause environmental pollution and land productivity decline. The existing garlic production method has three highs and one low of "high input, high output, high pollution and low efficiency". As a feature, garlic, as a commercial crop, has the following defects and deficiencies in the existing production methods: [0003] (1) Excessive fertilization is very common. The average amount of nitrogen fertilizer is more than 525kg / ha, which is 3-4 times the nitrogen demand of garlic. Therefore, how to reduce the amount of fertilization of garlic is an important issue under the condition of ensuring the yield of garlic. technical problems. [0004] (2) The existing cultivation methods of garli...

AI Technical Summary

Problems solved by technology

[0009] The technical problem to be solved by the present invention is to overcome the defects and deficiencies of the existing garlic cultivation methods such as plowing the soil moisture surface, which damages the soil structure to a greater degree, exposes the soil surface, reduces soil quality, excessive fertilization, and destroys biodiversity. , propose a protective cultivation method of garlic that can sustainably protect the soil and reduce environmental pollution, and at the same time save costs and increase efficiency
