Method utilizing coastal saline soil of Yellow River Delta to grow peanuts

Abstract

The invention relates to a method utilizing coastal saline soil of the Yellow River Delta to grow peanuts, which comprises the following steps: (1) building platform fields which are 0.08-0.10 hectare in area and are separated by a main drainage ditch and drainage ditches; (2) respectively applying smashed crop straw and thoroughly decomposed farmyard manure to the surfaces of the platform fields, and then deeply ploughing and leveling the platform fields to obtain the leveled platform fields; (3) irrigating the leveled platform fields to enable the depth of water of the earth's surface to be 10-15cm, and obtaining the platform fields to be ploughed; (4) performing rotary tillage to the platform fields to be ploughed, then making rectangular pieces of land in the fields, establishing low banks of earth between the fields, sowing the peanuts in the flat rectangular pieces of land in the fields, applying compound fertilizer of 900-1,200kg / hectare and calcium superphosphate of 600-800kg / hectare between the lines, and covering a mulching film after seeding; and (5) performing field management according to the prior art. By means of the method, the coastal saline soil is improved effectively and economically, and good economic benefits and environmental benefits are obtained.

Description

technical field [0001] The invention relates to a method for planting peanuts by using coastal saline soil of the Yellow River Delta, belonging to the technical field of agricultural planting. Background technique [0002] Peanut (Arachis hypogaea L.) is the main oil crop and economic crop in my country. The development of peanut industry has strategic significance for the development of my country's national economy and grain and oil security. However, my country's per capita arable land is limited, only 1 / 3 of the world's per capita. With the development of society and economy, the contradiction between man and land has become increasingly prominent, and the pressure to ensure the effective supply of agricultural products and food security has become increasingly serious. In order to avoid competition for land for grain and oil, it is imperative to actively explore effective methods for planting peanuts using the coastal saline soil of the Yellow River Delta.
