Problems solved by technology

Although this technology has many advantages, it can only be used for urban greening of saline-alkali flat land. If it is used for saline soil improvement of farmland, the cost of investment required by farmers is unacceptable. Therefore, a special technology for farmland saline soil improvement is invented. is very necessary

Embodiment 1

[0034] Embodiment 1: the comprehensive improvement method of salt-alkaline flat farmland soil and vegetation, it carries out soil improvement with a thickness of 0.4m on the ground surface on the plot to be improved, and specifically includes the following steps:

[0035] (1) Divide each plot to be improved into work blocks with a width of 20m and a length of several meters;

[0036] (2) Excavate the main blind ditch and branch ditch on the land to be improved. The main ditch is 0.3m×0.7m, and the branch ditch is 0.3×0.4; The ditch vertically intersects with the blind ditch of the branch water, which is in the shape of a fishbone; the main blind ditch is dug in the middle of each working section, and the two sides of each main ditch are to prevent the loss of natural rainfall Small square furrows, small square furrows should be made at every 10m on both sides of the main water blind ditch, and the soil moisture will be discharged into the branch water blind ditch according to ...

Abstract

The invention is concerned with complex improvement method for farm soil and vegetation to salina. It carries the improvement about the soil with 0.4 m thickness, relating to cutting piece, digging main pouring blind drain and branch pouring blind drain channel, making small square farmland filled with clear arsenolite, backfill soil and return to even, beat sand hole, making fall of slope, wash salt and eject salt, fertilization and tillage deeply. The improvement soil is fit for all kinds of crop, greensward and perennial flowers, and forms the soil for foodstuff crop, plant with shallow root and flowers. Its investment is low and the amount of a unit of area is at least 5000, and the improvement fee reduces greatly and it adds the plant area of farm and enhances the output of foodstuff and vegetable. It protects the soil resource to add the area of foodstuff planting, and it is an economic, extensive, simple and indirect technology for agricultural salina.

Description

(1) Technical field: [0001] The invention relates to a method for comprehensive improvement of soil and vegetation, in particular to a method for comprehensive improvement of soil and vegetation in saline-alkali flat farmland. (two) background technology: [0002] At present, the area of ​​farmland saline-alkali land in our country is quite large and the range is also very wide, so it has a great impact on the growth of crops, directly affects the output of food and vegetables, and brings certain obstacles to economic development. [0003] In 2004, we applied for a patent named "Water-saving saline-alkali flat land physical-chemical-ecological comprehensive improvement and vegetation construction technology", the patent application number is 200410072547.9 (published by the State Intellectual Property Patent Office on May 3, 2006), And obtained considerable economic and social benefits. Because it can not only prevent the country's land from being destroyed, but also reduce...
