Three-dimensional fertilizer applying method for crops

Abstract

The invention discloses a three-dimensional fertilizer applying method for crops. Fertilizers are applied to three three-dimensional spaces which are underground, ground and overground respectively, wherein a biological organic fertilizer is applied as a basic fertilizer in the underground three-dimensional space; a humic acid macroelement water-soluble fertilizer is applied as an additional fertilizer in the ground three-dimensional space; a trace element organic water-soluble fertilizer is applied as a leaf fertilizer in a spraying way in the overground three-dimensional space. The method has the advantages that the fertilizer utilization rate is increased, the yield of the crops is increased, the quality of an agricultural product is improved, the structure of soil is improved, and the breeding of harmful pathogenic bacteria in the soil can be inhibited; the popularization and application of the method are significant for reducing pest and disease damage, continuous cropping obstacles caused by continuous cropping and farmland pollution, protecting the ecological environment and ensuring the safety of an agricultural product.

Description

technical field

[0001] The invention belongs to the field of agricultural technology. Specifically relate to a method for three-dimensional fertilization of crops, Background technique

[0002] Fertilizer is an important means of agricultural production, which has made great contributions to the promotion of my country's agricultural development, especially the increase in grain production, while soil is the foundation of agriculture. Improper use of chemical fertilizers can lead to soil quality degradation and pollution, which directly threatens the reliability of agriculture. Continuous development. At the same time, excessive application of nitrogen fertilizer or partial application of nitrogen fertilizer will lead to a large amount of nitrate accumulation and downward leaching in the soil, which will become an important pollution source of water bodies, especially shallow groundwater. At present, agriculture has become an important source of greenhouse gas emissions. Th...

Embodiment 1

[0012] Test site: Suburbs of Hepu County, Beihai City

[0013] Crop Type: Banana

[0014] Fertilization program:

[0015] (1) Experimental treatment: apply base fertilizer, before planting bananas, combine soil cultivation with bio-organic fertilizer 75kg / mu and spread evenly in the soil; apply topdressing fertilizer, use humic acid macroelements water-soluble at 1.5 kg / time·mu in the middle and late growth period of bananas Fertilizer is watered 500 times, applied by artificial irrigation, applied twice, with an interval of 15 days; foliar fertilization, 30ml / mu organic water-soluble fertilizer 1500 times in the middle and late growth period of bananas, sprayed twice with an electric sprayer, with an interval of 7 days sky.

[0016] (2) Control treatment: 150kg of compound fertilizer per mu is evenly spread in the soil

Embodiment 2

[0021] Test location: Santang Town, Nanning City

[0022] Crop Type: Corn

[0023] Fertilization program:

[0024] (1) Experimental treatment: apply base fertilizer, before planting corn, combine with soil tillage to use bio-organic fertilizer 75kg / mu and spread evenly in the soil; apply topdressing fertilizer, use humic acid macroelements water-soluble at 0.75kg / time·mu in the middle and late stages of corn growth Fertilizer is watered 1000 times, applied by artificial irrigation, applied twice, and the interval is 15 days; foliage fertilization, 20ml / mu organic water-soluble fertilizer 2000 times liquid is sprayed twice with an electric sprayer, and the interval is 7 days sky.

[0025] (2) Control treatment: 150kg of compound fertilizer per mu is evenly spread in the soil

[0032] Fertilization program:

[0033] (1) Experimental treatment: base fertilizer is applied, and 80kg / mu of bio-organic fertilizer for soil cultivation is evenly spread in the soil before peanut planting; topdressing is applied, and 0.75kg / time·mu of humic acid is used in the middle and late stages of peanut growth. Dilute the fertilizer 400 times with water, apply it by artificial irrigation, and apply it twice, with an interval of 15 days; fertilize the leaves, and spray 1500 times liquid of organic water-soluble fertilizer 30ml / mu in the middle and late stages of peanut growth once with an electric sprayer.
