Abstract

The invention relates to the technical field of rice planting, and discloses a rice planting compound fertilizer capable of improving soil, the rice planting compound fertilizer comprises the following raw materials in parts by mass: 20-30 parts of a massive element fertilizer, 15-20 parts of a medium element fertilizer, 10-15 parts of a trace element fertilizer, 3-8 parts of biological bacteria,1-5 parts of a water-retaining sustained-release agent, 1-5 parts of a plant growth conditioner, 1-5 parts of a chelating agent and 12-49 parts of a filler; and the filler comprises bentonite, dregs,shrimp shell powder, medical stone powder, diatomite, light burned magnesium powder and rice husk ash. The invention also discloses a preparation method of the rice planting compound fertilizer capable of improving soil. According to the invention, the combination of a soil conditioner and the fertilizers can provide comprehensive and balanced nutrition required by rice, the fertilizer effect is rapid and lasting, the labor amount of farmers is reduced, time and labor are saved, heavy metals can be effectively prevented from being absorbed by crops, and the effect of treating the heavy metalsis achieved.

Description

technical field [0001] The invention relates to the technical field of rice planting, in particular to a compound fertilizer for rice planting capable of improving soil and a preparation method thereof. Background technique [0002] Rice (scientific name: Oryza sativa) is a kind of herbaceous Oryza sativa, and it is also the most important and longest food in Oryza genus. It is also called Asian cultivated rice, and it can be said to be rice in simple terms. Rice is the main food crop in my country and one of the important commodity grains in China. The sown area and total output of rice rank first among food crops, the sown area ranks second among the rice-producing countries in the world, and the total output ranks first in the world. The sown area of ​​rice in my country is basically stable at 30-31 million hectares, the total output is about 20,000 tons, and the output per unit area is 6300-6500 kg / ha. The sown area accounts for 20.2% of the total grain area, and the ou...

Problems solved by technology

However, judging from the current situation of rice development, there are still some common problems in rice planting in my country, which limit the development of rice planting.

At present, in the process of rice planting, there is a large demand for manpower, especially for bulk crops that need to be fertilized multiple times, which is not only labor-intensive and time-consuming, but also inconvenient for top-dressing crops in the late growth period, increasing production costs, and excessive fertilization will also deteriorate the soil quality , the soil with deteriorating soil quality not only affects the yield, but also reduces the dwindling area of ​​agricultural land in our country, which reduces the grain yield and forms a vicious circle
