Fertilizer specially used for enabling rice to turn green

Abstract

The invention discloses fertilizer specially used for enabling rice to turn green. The fertilizer is characterized by being prepared from the following raw materials: 60kg / ha of urea, 10kg / ha of silicon fertilizer, 5kg / ha of magnesium sulfate, naphthaleneacetic acid and biological bacteria powder, wherein the weight of the naphthaleneacetic acid accounts for 2 / 1000 of the weight of the fertilizer, the weight of the biological bacteria powder accounts for 3 / 1000 of the weight of the fertilizer, the mass percent of N in the urea is 46%, the mass percent of SiO2 in the silicon fertilizer is 20%, the mass percent of Mg in magnesium sulfate is 10%, the mass percent of mono-naphthaleneacetic acid in the naphthaleneacetic acid is more than or equal to 98%, and a mixed preparation of bacillus megaterium and bacillus mucilaginosus powder in the biological bacteria powder has an effective living bacteria number of more than or equal to 5 billion / g. Compared with the prior art, the fertilizer specially used for enabling the rice to turn green has the advantages that compared with the conventional fertilizer specially used for enabling the rice to turn green, the fertilizer provided by the invention is complete in formula nutrients; due to the combined action of quick-acting fertilizer and bacterial fertilizer, the fertilizer can improve the quality of rice seedlings, is rapid in seedling survival speed, increases the rice yield by 6% or above, and improves the economic benefit value.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a special fertilizer for rice turning green. Background technique [0002] Rice is native to tropical Asia, and after being widely planted in China, it gradually spread to all parts of the world. The rice grains produced by rice are called rice or rice after shelling. Nearly half of the world's population feeds on rice. Compared with other crops, The digestibility and absorption rate of nutrients contained in rice are relatively high, which is most suitable for the needs of the human body. After the introduction of rice in northern my country, due to the short growth period in the north and the low yield and poor quality of directly sown rice, rice in the north is cultivated in two stages. The first stage is the seedling raising period in greenhouses. At the Ye Yixin stage, transplant rice seedlings in the field and enter the second stage of cultivation. After rice seedlings are transplanted, aft...

Problems solved by technology

After transplanting rice seedlings, after 5-7 days of slowing down the seedlings, fertilizer should be applied immediately to promote the rice seedlings to turn green and survive as soon as possible. The conventional rice turning green fertilizer is mainly urea (nitrogen fertilizer). The variety of fertilizers is single and the nutrition is unbalanced, which is not conducive to the growth of rice seedlings.
