Embodiment 1
[0033] Experimental plot: Xizhaofeng Village, Yong'an Town, Kenli County, Dongying City, Shandong Province;
[0034] A method for planting peanuts utilizing the coastal saline soil of the Yellow River Delta, comprising the steps of:
[0035] (1) On November 3, 2009, 0.6 hectares of coastal saline soil located in Xizhaofeng Village, Yongan Town, Kenli County, Dongying City, Shandong Province was selected with loose soil, flat terrain, and convenient drainage and irrigation. A drainage ditch with a depth of 1.2m and a width of 1.5m is excavated every 20m in the vertical direction of the ditch. Except for a small dam with a height of 30cm and a width of 40cm, the excavated earth is evenly scattered on the main drainage ditch and the drainage ditch. 5 terraced fields with an area of 0.10 hectares separated;

Embodiment 2
[0056] The method described in Example 1, the difference is that,
[0057] In step (1), the experimental plot is coastal saline soil in Jingling Village, Kenli Sub-district Office, Kenli County, Dongying City, Shandong Province;
[0058] In step (4), the sown peanut variety is Huayu No. 20.
Embodiment 3
[0070] The method described in Example 1, the difference is that,
[0071] The sowing year is 2011;
[0072] In step (4), the sowing density of peanuts is 195,000 holes / ha.

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. [0003] The...
