Embodiment approach

[0033] 1. Effects of different plowing periods on the yield of milk vetch, the natural seedling emergence and yield of milk vetch after autumn.

[0034] The experiment was carried out in Yixing from October 2003 to May 2005. The milk vetch was sown on October 5, 2003, and the plowing period of the spring milk vetch in 2004 was set as A: April 22 (full flowering stage), B: May 10 (50% black pod stage), C: 5 June 22 (80% black pod period) and D: June 5 (full ripening period). To study the seed yield of different treatments of milk vetch and the effect on the natural seedling emergence and yield of milk vetch in the field after autumn.

[0035] Implementation Effect:

[0036] (1) Yield of milk vetch seeds harvested before different plowing periods

[0037] See Table 1 for the yield of milk vetch seeds in different harvest periods. It can be seen from Table 1 that except for milk vetch that was not plowed on April 22, the rest produced seeds, and the later the harvest, the high...

Abstract

The present invention discloses a Chinese milkvetch cultivation method in rice field, and relates to a Chinese milkvetch cultivation and utilization technique under the condition of paddy field rice-green fertilizer rotation cropping system. It is characterized by intersowing Chinese milkvetch seeds in the rice field, and adopting a series of measures of channelling and discharging water after the rice is harvested so as to implement said invention.

Description

technical field [0001] The invention relates to a method for cultivating milk vetch in paddy fields, which belongs to the cultivation technology of milk vetch in rice fields, and is suitable for planting and utilizing milk vetch under the condition of rice green manure rotation system. Background technique [0002] Due to the action of rhizobia, milk vetch can fix 5-10 kg of nitrogen in the air per mu per year. As a green manure crop, it has been planted in the middle and lower reaches of the Yangtze River in my country. By the 1970s, the planting area of ​​milk vetch in my country reached 100 million mu . The traditional planting and utilization technology of milk vetch in paddy fields is to sow seeds in the paddy fields every autumn, and sow them in the spring of the second year when they are in full bloom and use them as green manure. It needs to be sown every year, and the labor cost for seeds is relatively high. Because milk vetch is used as green manure, There is no di...
