Embodiment Construction

[0032] The specific implementation manner of this patent will be further described in detail below.

[0033] The first step, Daejeon selection

[0034] In the one-season rice area, rice fields with a rice yield higher than 7 t / ha and convenient irrigation and drainage are selected for continuous planting. At the same time, the distance between different milk vetch varieties should be kept more than 2 kilometers.

[0035] The second step, seed treatment

[0036] In order to improve the vigor of milk vetch seeds and promote seed germination, put the milk vetch seeds in the sun for half a day to one day 1-2 days before sowing. Mix the seeds and fine sand according to the ratio of 2:1, then put them in a woven bag and knead for 5-10 minutes to scrape the seed coat of the milk vetch. Scratching the seed coat with fine sand can accelerate the water absorption of the seeds and increase the germination potential. Pour milk vetch seeds into salt water with a specific gravity of 1.05...

Abstract

The invention provides an astragalus sinicus single-season rice high-yield efficient seed reservation method which comprises the following steps: a, selection of astragalus sinicus seeds: before sowing, selecting the same variety of astragalus sinicus so as to prevent other varieties of astragalus sinicus from being planted in a range within 2 kilometers; b, treatment of the astragalus sinicus seeds: before sowing, insolating the astragalus sinicus seeds in the sun for half a day to one day, then peeling, selecting the astragalus sinicus seeds through a salt soaking method, and finally washing away the salt on the astragalus sinicus seed with clean water; c, sowing: before sowing, digging a perimeter ditch in a field, and then sowing uniformly; d, field monitoring before harvesting of seeds: performing prevention and control on weeds and disease and insect damage; e, harvesting of the seeds: harvesting by virtue of manual power or a combine harvester, wherein harvesting is performed when the black legume rate of the astragalus sinicus is up to 85% during manual harvesting, and harvesting is performed when the black legume rate of the astragalus sinicus is up to 90-95% during harvesting based on the combine harvester. The method has the characteristics of being high in seed yield, promoting the rapid recovery and development of southern green manure crops, improving the soil fertility, reducing the application amount of fertilizers, protecting the ecological environment and the like, and can be used for not only improving the double-cropping index of the rice field and improving the income of farmers, but also achieving a soil fertility effect.

Description

technical field [0001] The invention relates to a high-yield and high-efficiency seed retention method of milk vetch in one-season rice fields. Background technique [0002] Milk vetch is a green manure variety planted in large areas in southern rice areas. It has the functions of fixing nitrogen and increasing fertilizer, improving soil fertility, and improving the environment. It has played an extremely important role in my country's agricultural production for thousands of years. Before the large-scale application of chemical fertilizers, the production and utilization of milk vetch made a significant contribution to increasing grain production and agricultural development in southern my country. Since the 1980s, due to the large-scale labor input required for the cultivation of milk vetch, the breeding of milk vetch lacks large-scale technology, and the planting area of ​​milk vetch has declined rapidly under the background of a large number of rural labor transfers in m...
