Problems solved by technology

Sowing milk vetch during this period will easily cause the soon-mature grains on the ears of rice to fall off due to human walking, resulting in a decrease in yield; 1 labor force can only sow 15 mu per day
Traditional sowing is labor-intensive, which seriously affects farmers' enthusiasm for planting milk vetch

Embodiment 1

[0029] Select Ganshan Township, a double-cropping rice production area in Changsha County, choose the same field, divide it into 3 parts, and sow milk vetch at the end of tillering stage, full heading stage and traditional 15 days before harvest. The experimental variety is Xiangfei No. 3, and the seed sowing rate is 2.0 kg per mu. Carry out field management after sowing according to the five steps above.

[0030] Sowing milk vetch at different times affects the growth and fertility of milk vetch. Compared with rice sowing 15 days before harvest, sowing at the end of tillering stage and full-heading stage both increased the days of the whole growth period, and the time of emergence, initial branching, flowering, full flowering and maturity were advanced.

Embodiment 2

[0043] 1. Select Xinhua Town, the double-cropping rice production area of ​​Yuanjiang City, select a normal-growing late rice field and divide the rice field into three parts, and separate the rice into working rows with bamboo poles before sowing.

[0044] 2. Sow Vetch at the end of tillering stage, heading stage and 15 days before harvest. The test variety was Xiangfei No. 3. The seeds were soaked in warm water for 3 hours before sowing, and then inoculated with liquid rhizobia, and then air-dried.

[0045] 3. Light machinery is used for sowing, and the seed sowing rate is 2.0 kg per mu. Drain the water in the field before sowing at the end of tillering and full-earning stages, and perform conventional late rice operations after sowing; traditional operations are used for sowing 15 days before harvest.

[0046] 4. The late rice is harvested with a full-feed rice combine harvester, and the header is 45cm from the ground. Use a rake to remove the piles of straw after harvestin...

Abstract

The invention discloses an early sowing method for the rice field milk vetch. The early sowing method for the rice field milk vetch comprises the following steps: a) sowing the milk vetch: in the late rice tillering last stage to the full heading time, sowing the milk vetch with the sowing amount of 2.0-2.5kg per unit of area when the field water content is less than 15%; b) managing field water: after sowing, keeping the field water content at 10-40%, opening a ridge ditch hole to discharge water after the milk-ripe stage of the late rice, ensuring that the field is under the drying state when the rice is harvested, then, harvesting the late rice by the harvester, regulating distance between the header of the harvester and the ground to be 45-55cm when the late rice is harvested, and evenly spreading the accumulated straw in the field after the rice is harvested; and c) ditching a land for growing field crops: after the late rice is harvested, digging a surrounding ditch around the field by a ditcher to ensure that the highest water level of the field does not exceed 0.5cm. The early sowing method for the rice field milk vetch, which is disclosed by the invention, is combined with the necessary farm operation of the rice in the rice growth period when the rice field operation is convenient, and water management is reasonably carried out to simplify the milk vetch sowing.

Description

technical field [0001] The invention relates to an early sowing method of milk vetch in paddy fields. Background technique [0002] Milk vetch is a very important fertilizer resource in agricultural production in southern rice areas. In the past, it played a very important role in maintaining soil fertility and promoting the development of planting in southern rice areas. Since the 1970s, due to the transfer of rural labor force and the large-scale promotion of chemical fertilizers, the planting area of ​​milk vetch in the south has gradually shrunk. In recent years, the large-scale application of agricultural machinery has reduced the labor intensity of milk vetch pressing greens; at the same time, the disadvantages of chemical fertilizer agriculture have gradually become prominent, and people's understanding of ecological agriculture has gradually improved, and milk vetch is reducing the use of chemical fertilizers and protecting cultivated land. The restoration and devel...
