A kind of seedbed raising method of early rice

Abstract

The invention discloses a seedbed seedling culture method for early rice. The method includes the steps of matrix preparation, seed soaking and pregermination, sowing, bed surface management and seedling lifting. Compared with the prior art, the method has the following advantages that fermented straw, horse dung and algae are adopted in a matrix and used in cooperation with remaining residues and the like used as edible fungus cultivation materials, high antibacterial performance is achieved, use of disinfestant is reduced, environment friendliness is achieved, and the transplanting standard can be met after seedlings are cultured for 25 days; incineration ash of combusted traditional Chinese medicine contains certain mineral substances and is mixed with the seedling culture matrix in proportion, and anti-bacterial and insect-resistant effects are achieved; in the management process of the seedling culture matrix, fertilizer and water, seedling culture cost is reduced, and meanwhile certain labor intensity is relieved; the growth vigor of the roots of the seedlings is good, continuous seedling pieces can be easily formed, transplanting operation is facilitated, seedling recovering after transplanting is rapid, the seedling quality is good, and insect-resistant and disease-resistant capacity is high.

Description

technical field [0001] The invention belongs to the technical field of agricultural breeding, and in particular relates to a bed seedling raising method for early rice. Background technique [0002] The distribution area of ​​rice planting in China is mainly in the south, and rice production is increasingly concentrated in advantageous areas. In recent years, my country's rice production has gradually concentrated in the middle and lower reaches of the Yangtze River and Heilongjiang rice production areas. At present, the southern rice area accounts for about 94% of my country's rice planting area , The area of ​​rice in the Yangtze River Basin has accounted for 65.7% of the country's total, of which early rice is produced in 13 provinces (regions), and the sown area is relatively large. However, due to the difficulty of controlling the temperature during the sowing period, if it is not properly managed, it will usually cause rotten seeds and rotten buds. Therefore, at present...

Problems solved by technology

However, due to the difficulty of controlling the temperature during the sowing period, if it is not properly managed, it will usually cause rotten seeds and rotten buds. Therefore, at present, seedlings are often raised before cultivation to improve the survival rate of early rice. The plant height grows, but its quality is poor, the dry matter of stems and leaves is less, and the taste of the rice planted is poor. If it is used for industrial grain or grain reserve, if it cannot be used in time, it will often cause waste, and the planting industry will outweigh the gains. Therefore need a kind of seedling raising method that can improve early rice quality

[0003] In the current seedling raising methods, the common problem is that the proportion of compound fertilizer is not appropriate, and when the early rice matures, the temperature is too high. If the amount of nitrogen fertilizer used in seedling raising is high, the seedling rate will be reduced, resulting in poor quality of the obtained seedlings.
