The terrain is hilly with a slope height of 295m , the slope is 20 to 25°. The soil type is yellow loam, pH 6.41, total nitrogen 1251mg / kg, alkaline hydrolyzable nitrogen 109.32mg / kg, available phosphorus 4.8mg / kg, available potassium 0.46mg / kg, and organic matter 20780mg / kg. The biogas fertilizer for test is a liquid biogas fertilizer with a dry matter content of 15% after the pig manure-straw mixed raw material biogas fermentation of the pig farm in Jiangjin test base, and the biogas fertilizer is sheared and homogenized by a biogas residue pump. The nutrient content of the biogas fertilizer is: organic matter content 68.5g / kg, total N content 5.24g / kg, total P content 1.85g / kg, total K conten...

Embodiment 2

[0042] (2) Using the mountain terrain to irrigate liquid fertilizers by gravity

[0043] (1) The test site is located in a tea mountain planting base (26°83'N, 106°59'E) in Jiuchang Town, Xiuwen County, Guiyang City, Guizhou Province. The soil type is yellow loam, pH 6.45, total nitrogen 1450mg / kg, alkaline hydrolyzable nitrogen 103.56mg / kg, available phosphorus 4.5mg / kg, available potassium 0.85mg / kg, and organic matter 21300mg / kg. The biogas fertilizer tested is mainly based on local pig manure and some crop straws as fermentation bases. The biogas slurry in the discharge room of the biogas digester with normal gas production for more than 3 months has a pH of 7.43, total nitrogen 1.07g / L, and total phosphorus. 0.10g / L, total potassium 2.67g / L.

[0044] The test time is from September 2020 to May 2021. According to the mountain topography, plant (mainly tea tree) coverage and watering needs of the test site, plan the artesian route, build a liquid storage tank on the top of...

Embodiment 3

[0049] (3) Using the plain terrain to irrigate liquid fertilizers by gravity

[0050] (1) The plain was selected as the operation area. The test site was located in a cotton planting base (30°04'N, 112°42'E) in Jiangling County, Jingzhou City, Hubei Province. The pH is 6.86, total nitrogen is 1982mg / kg, alkaline hydrolysis nitrogen is 193.61mg / kg, available phosphorus is 6.7mg / kg, available potassium is 1.74mg / kg, and organic matter is 30025mg / kg. The biogas fertilizer tested is the biogas slurry fermented in the local pig farm biogas digester, and the nutrient content is: organic matter 2.59%, total nitrogen 0.45%, available phosphorus 0.16mg / kg, available potassium 0.99mg / kg, pH 7.1, humic acid 0.18% .

Abstract

The invention provides a self-flowing type shock wave spray-explosion deep scarification and deep application operation method suitable for liquid fertilizer, which is characterized in that a self-flowing type shock wave spray-explosion deep scarification and deep application operation system is constructed according to natural landforms, and self-flowing type precise deep application of the liquid fertilizer is realized through the self-flowing type shock wave spray-explosion deep scarification and deep application operation system. The self-flowing type deep application operation system comprises a fertilizer storage device, a fertilizer conveying device, a fertilizer collecting device and a fertilizer deep application channel; and the fertilizer storage device is used for storing liquid fertilizer. According to the method, natural landforms can be well utilized, self-flowing type deep application operation in high mountains or hills and other zones is achieved, a large amount of labor force and complex machines are not needed, high deep application operation cost is not needed either, and the utilization rate of fertilizer is greatly increased.

Description

technical field [0001] The invention belongs to the technical field of precise deep application of fertilizers, and in particular relates to a self-flow shock wave blasting and deep soil application operation method suitable for liquid fertilizers. Background technique [0002] Most of the traditional fertilizer application methods are to use manual or spreader to spread the material on the soil surface, and then use the tractor and other power equipment to drive the rotary tiller and other operating equipment to mix the material spread on the surface into the soil, or use excavators, Forklifts and other engineering equipment are equipped with relevant equipment to mix and mix various materials into the soil layer. These operating methods mainly focus on fertilizing in the shallow surface layer of the soil, and have the following shortcomings: (1) destroying the surface soil and soil aggregate structure; (2) There are many limitations to the operation, including the topograp...
