Embodiment 1

[0014] The test field is selected from the farmland of farmers in Luwang Village, Yujiang County, Yingtan City, Jiangxi Province. The test is divided into two treatments, each with 3 repetitions, and the area of ​​each treatment is 14×3m 2 , arranged randomly. Before sowing peanuts, after fine soil preparation, ditch about 5 cm deep. Wheat straw residue (pH=10, total nitrogen content is 0.30%, total phosphorus content is 0.75%, total potassium content is 6.5%, carbon content is 14%) and wheat straw ash (pH=8.5, total nitrogen content is 0.30 %, the total phosphorus content is 0.35%, the total potassium content is 3.0%, and the carbon content is 15%) according to the mass ratio of 3:7, and then mixed with water-retaining material sodium polyacrylate according to the mass ratio of 5:1 to form a combination Plants, together with the base fertilizer (20 kg of urea, 50 kg of superphosphate, 22.5 kg of potassium chloride), the dosage of the composition is 50 kg per mu. Then plant ...

[0019] The test field is selected from the farmland of farmers in Luwang Village, Yujiang County, Yingtan City, Jiangxi Province. The test is divided into two treatments, each with 3 repetitions, and the area of ​​each treatment is 14×3m 2 , arranged randomly. Before sowing peanuts, after fine soil preparation, ditch about 5 cm deep. Rice straw residue (pH=9.6, total nitrogen content is 0.26%, total phosphorus content is 0.69%, total potassium content is 6.1%, carbon content is 12.3%) and rice straw ash (pH=9.1, total nitrogen content is 0.42 %, the total phosphorus content is 0.39%, the total potassium content is 4.1%, and the carbon content is 18%) according to the mass ratio of 5:5, and then mixed with the water-retaining material sodium polyacrylate according to the mass ratio of 8:1 to form a combination Plants, together with the base fertilizer (20 kg of urea, 50 kg of superphosphate, 22.5 kg of potassium chloride), the dosage of the composition is 50 kg per mu. Then p...

Abstract

The invention discloses composition for increasing the yield of dry land peanuts and a usage method. The composition comprises straw residues, straw ash and a water-retention material, wherein the mass ratio of the straw residues to the straw ash is in a range of 3:7-7:3, and the mass ratio of a mixture of the straw residues and the straw ash to the water-retention material is in a range of 5:(1-20):1. Biomass power generation waste in the composition has rich nutrient elements, can supplement the peanuts with elements required by growth of the peanuts and can improve acid soil; the water-retention material contained in the composition can prevent drought and water shortage of the peanuts in the growth period. The composition can promote growth of peanut plants, enlargement of root systems, increase of fresh weight of nuts of each single plant after applied to the peanuts, and finally, the yield of the peanuts is increased by more than 13%.

Description

technical field [0001] The invention provides a composition and a use method for increasing the yield of peanuts in dry land, which belongs to the intensive agricultural production technology and is specially used for increasing the yield of peanuts in acidic soil. Background technique [0002] Red soil dryland is an important agricultural soil resource in southern my country, and has always been the focus of development and utilization research. With the rapid development of agriculture and the increase of fossil fuel consumption, the problem of soil degradation in this area is becoming more and more serious, mainly manifested in soil compaction, erosion, acidification, element imbalance, chemical pollution, loss of organic matter and degradation of flora and fauna, etc. The problem seriously limits the development of land productivity. For the improvement of soil acidification, the main purpose of improvement is to reduce the amount of soil exchangeable acid, and the ap...
