Special high-efficiency weeding striking root fertilizer for paddy rice

Abstract

The invention provides a special high-efficiency weeding striking root fertilizer for paddy rice. The fertilizer is prepared from the following components by weight: 55 to 65 parts of a nitrogen fertilizer, 4 to 6 parts of sea mud, 0.5 to 1.5 parts of tobacco, 1.5 to 2.5 parts of a selenium-rich additive, 1 to 2 parts of a herbicide, 1 to 2 parts of pig bone, 15 to 25 parts of straw powder, 0.5 to 1.5 parts of red yeast, 0.4 to 1 part of compound sodium nitrophenolate, 1 to 2 parts of tea residue, 4 to 6 parts of potassium fulvate, 0.4 to 1 part of shell powder, 1 to 2 parts of waste dreg of pleurotus eryngii, 1 to 2 parts of olive residue, 1 to 2 parts of zinc sulfate, 1.5 to 2.5 parts of modified corn starch and 0.2 to 0.4 part of fennel powder. The fertilizer has weeding rate of more than 95%, and the green-returning rate of paddy rice in 3 d reaches 100%; the fertilizer has strong fast dissolving capability and can be dissolved within 10 min; a fertilized paddy rice plant is strong, has a great number of tillers and plump grains and can realize yield increase and income increase; and rice cultivated by using the fertilizer contains organic selenium easily absorbable by the human body and has the advantages of edible safety and high biological efficiency.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a special high-efficiency weeding and regreening fertilizer for rice. Background technique [0002] Rice is the main food crop in my country, and the population whose staple food is rice accounts for about 50% of the total population. my country's rice planting area reaches 29.96 million hectares, with a vast distribution area. Due to historical reasons such as food pressure, my country's rice production used to aim at high yield, and paid less attention to the content of rice microelements. With the increasing living standards of residents and the development of foreign trade, the development of microelement-enriched rice technology will continue to grow. received more attention. [0003] At present, rice special fertilizers containing zinc, silicon, calcium, magnesium and other medium and trace elements are usually used once when transplanting rice seedlings. It has the...

Problems solved by technology

It has the characteristics of turning green quickly and promoting effective tillering, but it has the defect of insufficient stamina, especially because the high fertilizer efficiency in the early stage promotes the growth of rice and also promotes the growth of weeds. The special fertilizer for rice in the prior art has no weeding effect. and the technical problems of promoting the rapid growth of rice in the later stage of turning green
