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

Embodiment 1

[0039] Before as paddy rice, (also can plant garlic by the method of the present invention in dry land), the sowing time of garlic is about 7 days after paddy harvest, broad bean ( Vicia faba L.) or peas ( Pisum sativum L.) The sowing time is synchronized with that of garlic.

[0040] Step 1: Harvesting of previous crops and preparation of covering materials

[0041] After the rice is harvested, the rice straw is cut and kept in the field. Due to the large demand for rice straw, which is 15t / ha, it is necessary to reserve twice the rice straw per unit area as the mulch discretion. The straw can be stacked in a corner of the farmland.

[0042] Step 2: No-tillage on soil moisture surface, excavation of irrigation and drainage ditches

[0043] After cutting the previous crop straw, no-till the soil moisture surface to minimize the disturbance to the soil, with every 50m×20m as a moisture surface unit, between two moisture surfaces, use manual or mechanical opening The way ...

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 involves the field of agricultural environmental protection technology, which is specifically a protective method for garlic. Background technique [0002] Garlic of the existing technology ( A.SATICUM L.) The production method is unsustainable. It will bring environmental pollution problems and the decline in land productivity. The existing technology of garlic production method is "high input, high output, high pollution and inefficient"It is characterized by the characteristics, as a economic crop, in the existing production method, there are the following defects and deficiencies: [0003] (1) Excessive fertilization is very common. The average dosage of nitrogen fertilizers is above 525kg / ha, which is 3-4 times the demand for garlic nitrogen. Therefore, how to reduce the amount of fertilization of garlic under the condition of ensuring garlic yield is an important way to reduce garlic.Technical issues. [0004] (2) The existing cultivatio...
