Embodiment Construction

[0014] The present invention will be further described below:

[0015] First, efficient mode:

[0016] Early rice will be broadcast live around April 10, and harvested with a harvester before July 15; late rice will be broadcast live from July 15 to 20, fully eared before September 20, and harvested with a harvester before October 25; safflower seeds will be harvested in late September It will be broadcast live in the late rice clusters in early October, and the early rice will be turned and retting about 12 days before direct broadcast as green manure.

[0017] Second, high-yield cultivation techniques:

[0018] 1. High-yield cultivation techniques for direct direct seeding of early rice

[0019] 1.1 Variety selection

[0020] It is advisable to choose varieties with strong cold resistance, high quality, high yield, early to mid-maturation, and good resistance at the seedling stage, such as "Zhefu 802", "Xiangzaoxian 6", "Liangyou 42", "Liangyou 287" and other varieties ....

Abstract

The invention discloses a high-yield cultivation method for direct seeding of early-season rice, direct seeding of late rice and clover seeds. The method comprises following steps: 1, direct-seeding of early-season rice around April.10th and harvest by utilization of a harvester before July.15th; 2, direct-seeding of late rice from July.15th to July.20th and full heading before September 20th and harvest by utilization of the harvester before Oct.25th; 3, direct-seeding of clover seeds in late-rice fields from the last ten days of September to the first ten days of October, retting early-season rice as green manure before direct seedling around 12 days. The method further comprises step 1, high-yield cultivation technology of direct seeding of early-season rice; step 2, high-yield cultivation technology of direct seeding of late-season rice; step 3, high-yield cultivation of clover seeds. The high-yield cultivation method for direct seeding of early-season rice has following features: a good mode of output, quality and efficiency can be fully represented; and labor is saved, rice seedling beds, fertilizers, medicine and water are saved; soil is improved; rice quality is good, output and income are increased.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and more relates to a high-efficiency model and high-yield cultivation method of early rice direct seeding-late rice direct direct seeding-safflower seeds. Background technique [0002] In recent years, with the sharp decline of the rural labor force and the relatively low benefits of growing grain, farmers' enthusiasm for growing grain has dropped significantly. At the same time, for the sake of convenience, farmers generally use chemical fertilizers as the mainstay. Long-term large-scale use of chemical fertilizers has brought serious pollution to farmland, resulting in soil compaction, barrenness, acidification, heavy metal content exceeding the standard, and soil fertility decline. How to carry out light and simplified cultivation, improve the soil, and increase food production requires innovation in the existing planting model. Safflower seeds have the advantages of fertilizing soi...
