Simple normalization seedling cultivation method for rice transplanted by machine without dish

Abstract

The invention discloses a diskless simple normalized seedling raising method for machine-transplanted rice, which belongs to the technical field of raising seedlings. The method comprises the following steps: 1. selecting variety; 2. treating seeds; 3. preparing rice seedling beds; 4. laying frames; 5. laying mulching films; 6. applying base fertilizer on rice seedling boards; 7. preparing screen mesh; 8. putting soil on the boards; 9. sowing in due time; 10. managing the rice seedling beds; and 11. taking and transplanting rice seedlings, and the like. By adopting a diskless simple normalized seedling raising technique, the method has the advantages of low production cost and high production efficiency.

Description

technical field [0001] The invention relates to a discless, simple and standardized seedling raising method for machine-transplanted rice, which belongs to the technical field of seedling raising methods. Background technique [0002] Rice is the most important food crop in my country and plays an important role in agricultural production. With the development of the rural economy, the area of ​​arable land available for rice planting is declining. Stabilizing the area of ​​rice planting is an important support for ensuring food security, and the breakthrough lies in expanding the area of ​​early rice and continuous cropping late rice. The key to expanding double-cropping rice planting area is to reduce farmers' planting costs and improve economic benefits. Practice has proved that mechanized rice seedling raising and transplanting technology has obvious cost-saving and benefit-enhancing effects. Therefore, further exploration and research on the seedling raising technology...

AI Technical Summary

Problems solved by technology

At present, the rice machine-transplanting varieties popularized in various places are not uniform, and the machine-transplanting varieties must be screened and combined to form the leading varieties suitable for rice machine-transplanting;

[0005] 2. There is a problem of insufficient seedlings for double-cropping rice machine transplanting. Compared with about 20,000 clumps of seedlings per acre for manual transplanting, the current rice transplanter machine transplants about 15,000 clumps of late rice seedlings.

[0006] 3. The current seedling raising technology of rice machine transplanting is mainly industrial seedling raising, and there is a problem of high one-time investment in the promotion process

The investment in supporting equipment such as seedling trays and seedling raising lines has reached a ratio of 1:1 with the rice transplanter, resulting in high seedling raising costs; it is difficult to store a large number of seedling trays required for industrial seedling raising, and a large number of warehouses are required. Machine transplanting of 250 mu of rice requires 5,000 sheets Seedling tray calculation, it needs to occupy nearly 50m 2 In addition, the industrialized seedling raising technology is cumbersome to operate, requires a large amount of loess, and uses a large number of equipment such as soil crushers and soil sieving machines, which is not suitable for large-scale promotion. It is necessary to explore a simpler and more suitable method for promotion machine-transplanted seedling raising technology;
