Point-to-point land improving and water saving planting method

Abstract

The invention discloses a point-to-point land improving and water saving planting method. The method comprises the following steps: 1. firstly, digging wide ditches or wide pits uniformly on the land at intervals, wherein the interval between the ditches or between the pits is 3-5 meters; 2. then digging narrow ditches or narrow pits at the bottoms of the wide ditches or the wide pits respectively, laying waterproof breathable films at the bottoms of the narrow ditches or the narrow pits respectively and putting the plant seeds on the two opposite side walls of the narrow ditches or the narrow pits respectively; and 3. filling soil and compound fertilizers, which are mixed uniformly, into the narrow ditches or the narrow pits, elevating the top surface of the soil until the middle parts in the wide ditches or the wide pits and then laying mulching films on the top surface of the soil. The method is especially suitable for vast sandy wasteland regions and is beneficial to afforestation or construction of desertification regions and improvement of the land utilization rate.

Description

technical field [0001] The invention relates to a method for soil improvement and planting of crops, in particular to a strip-type land improvement and water-saving planting method. Background technique [0002] With the rapid development of the social economy, urbanization, industrialization, transportation and other non-agricultural constructions occupy a large amount of cultivated land, and the land has not increased for a long time. The decline in soil fertility has degraded the quality of the grown food and agricultural by-products. These phenomena threaten people's survival. There is a vast amount of undeveloped desertified land in the northwestern region of my country. If these idle land can be developed and utilized, the pressure brought about by the decrease in the number of cultivated land will be effectively alleviated. Contents of the invention [0003] The purpose of the present invention is to provide a point-and-point land improvement and water-saving plan...
