Vertical and deep hole cultivation method for farmland

Abstract

The invention relates to a farmland cultivation method, particularly relates to a vertical and deep hole cultivation method for a farmland, and is used for solving the defects of the existing cultivation method. The vertical and deep hole cultivation method in the farmland comprises the following steps of: a. carrying out vertical and deep hole cultivation according to preset planting holes, wherein the depth of the cultivation holes is 50-100 cm and the diameter of the cultivation holes is 8-20 cm; b. after cultivation is finished, filling the cultivation holes with mixed farmland surface soil and crop special fertilizer, and then sufficiently irrigating with water before sowing; c. sowing or cultivating crops in the cultivation holes by adopting a rare-hole and dense-plant planting manner, wherein 3-5 plants are planted in each hole; and d. carrying out hole irrigation and water replenishing operation during the crop growth. According to the invention, local hole forming, local fertilization and local irrigation are used as a technical line, and a local hole sowing, hole application and hole irrigation manner is adopted to directly apply water and fertilizer to the centralized layer of the crop root system, thus soil surface evaporation and gravity water loss are effectively reduced, and the purposes of efficiently utilizing water and fertilizer, and improving water productivity and utilization rate of the fertilizer are achieved.

[0001] The invention relates to a farmland cultivation method, in particular to a farmland vertical deep hole cultivation method. Background technique

[0002] my country is a country with a large population and food consumption, and food security is the focus of the world. my country's per capita arable land resources are few, but most of the arable land is rich in heat resources. Intensive farming and multiple cropping are the main technical measures for increasing grain production in my country. Increasing grain production has always been the focus of my country's agricultural production. Reforming farming and cultivation methods, increasing the multiple cropping index, and striving to increase per unit yield are important ways of grain production.

[0003] Tillage is the basis of crop cultivation. Cultivation can improve the soil structure, make the soil in the root layer of the crop moderately loose, form a good aggregate structure, so as to absorb and...
