Rice seedling culture fertilizer

Abstract

The invention provides a rice seedling culture fertilizer, which is prepared from 18 to 20g of chitin, 200 to 350g of total water soluble potassium fulvic acid, 80 to 150g of lumbrukinase stock solution, 20 to 50g of citric acid, 100 to 150g of superphosphate, 200 to 450g of monoammonium phosphate and 70 to 100g of zinc sulfate through uniform stirring. In the use process, the fertilizer and waterare diluted according to the ratio of 1:1000. A great number of organic matters, macro elements and trace elements are contained; the nutrients required by the growth and development period of rice seedling can be met; the effects of improving the seedling quality and improving the disease and insect pest resistance capability are achieved. The product is a whole water-soluble rice seedling fertilizer; in the use process, the fertilizer and water are diluted according to the proportion of 1:1000; after soil is laid on a seedling culture disc, the diluted seedling culture fertilizer is used for spraying and seeping the soil on the seedling culture disc; the complicated soil fertilizer mixing work is avoided; the operation is simple; the implementation is easy; wide prospects are realized in the rice seedling culture work.

Description

technical field [0001] The invention belongs to agricultural production technology, and in particular relates to a rice seedling raising fertilizer. Background technique [0002] The invention relates to a rice seedling raising fertilizer. It solves the problems of low nutrient element content, large amount per unit area, and high production and transportation costs in the currently used rice seedling raising soil, and also reduces the labor intensity of fertilization and the process of using fertilizer. [0003] Rice is one of the most important food crops in my country. The country's rice planting area accounts for about 30% of the grain crop area, and its output is close to half of the total grain output. At present, rice planting basically adopts the method of raising seedlings in greenhouses first, and then transplanting seedlings in the field to achieve the effect of increasing production and harvest. Nowadays, seedlings are raised in greenhouses, and the soil in ea...

Problems solved by technology

Nowadays, seedlings are raised in greenhouses using seedling trays, and the soil in each seedling tray must be fully mixed with the seedling soil. This is a heavy task for rice growers, and there is an urgent need for a technology that can reduce this part of the labor.
