Problems solved by technology

[0002] Heilongjiang Province is the main production area of ​​high-quality rice in my country. The product quality is good and the market competitiveness is strong. However, at present, most of them are raised and transplanted. 400 cubic meters of water is required, and the ditches are flooded with more than 500 cubic meters), the intensity of non-point source pollution is high, and the amount of fertilizer and medicine is large, which makes it difficult to expand the planting area.
[0003] At the same time, due to the large amount of corn planted in Heilongjiang Province, but its products are not competitive in the market, it is imperative to adjust and reduce the corn area after the country cancels the protection price, but it is facing the problem that the existing rice cannot expand the planting area on a large scale. question

Embodiment 1

[0040] A cold area rice direct seeding drip irrigation cultivation method, comprises the following steps:

[0041] A. Seed breeding: select the long-grain rice varieties in the lower limit of the planting area or the next accumulated temperature zone for planting, and use a coating agent to coat the seeds, and dry and store the seeds after coating;

[0042] B. Soil preparation: plow and rake the ground in autumn, and level the ground in the spring of the second year;

[0043] C. Sowing: After leveling the land, use an air-suction precision seeder to sow rice seeds in holes, and at the same time complete side-depth fertilization. The sowing width is 1.6m, and 8 rows are sown in each sowing width, between two adjacent rows. The distance between them is 10cm and 30cm successively, and 12 seeds are sowed in every hole; Laying drip irrigation pipe while sowing, and use described drip irrigation pipe to irrigate in the whole growth cycle of paddy rice;

[0044] D. Field management:...

Abstract

The invention relates to a cold region rice direct seeding drop irrigation cultivating method. The method comprises the following steps of seed breeding, soil preparation, sowing and field management. In the soil preparation step, plowing and harrowing are carried out in autumn, and land formation is carried out in spring of next year; a drip irrigation pipe is laid while sowing, and the drip irrigation pipe is used for drip irrigation in the whole growth period of rice. According to the scheme that rice can be planted in a cold region on a large scale, especially the method can be popularized in a rolling hill and cultivated land not suitable for being conventionally developed for rice planting, the rice planting area in the cold region can be effectively increased, and the method has milestone significance on solving the planting structure adjusting problem.
