Embodiment 1

[0031] The late rice is sown in June of the first year, and the late rice is transplanted into the paddy field in July of the same year, and the mature late rice is harvested in October.

[0032] Eight days before harvesting mature late rice, dry the milk vetch seeds of Yujiang big leaf seed for 4 hours, mix them with fine sand at a ratio of 1:1, then moisten them with water, put them in a cloth bag and rub them repeatedly to remove the seed wax stratum. Then, remove the diseased grains and empty grains in the seeds with a concentration of 2% salt water. Finally, soak the seeds with 0.2% ammonium molybdate solution for 18 hours.

[0033] Dry and soak the milk vetch seeds, according to the sowing rate of 30kg / hm 2 After being mixed with the calcium magnesium phosphate fertilizer and soil miscellaneous fertilizer that application rates are respectively 5kg / mu and 20kg / mu, sow in the above-mentioned paddy field with the thin water layer of 1cm thickness. At the late tillering ...

Embodiment 2

[0037] The late rice is sown in June of the first year, and the late rice is transplanted into the paddy field in August of the same year, and the mature late rice is harvested in October.

[0038] Twelve days before the harvest of mature late rice, dry the milk vetch seeds of Yujiang big leaf seed for 5 hours, mix them with fine sand at a ratio of 1:3, then wet them with water, put them in a cloth bag and rub them repeatedly to remove the seed wax stratum. Then, remove the diseased grains and empty grains in the seeds with a concentration of 3% salt water. Finally, soak the seeds with 0.2% ammonium molybdate solution for 32 hours.

[0039] Dry and soak the milk vetch seeds, according to the sowing rate of 45kg / hm 2 After being mixed with the calcium magnesium phosphate fertilizer and soil miscellaneous fertilizer that application rate is respectively 5kg / mu and 25kg / mu, sow in the above-mentioned paddy field with the thin water layer of 2cm thickness. At the late tillering...

Embodiment 3

[0043] The late rice is sown in June of the first year, and the late rice is transplanted into the paddy field in mid-July of the same year, and the mature late rice is harvested until October.

[0044] Ten days before the harvest of mature late rice, the seeds of milk vetch of Yujiang big-leaf seed were dried for 4.5 hours, then mixed with fine sand at a ratio of 1:2, and then the waxy layer of the seeds was removed with a rice mill. Then, remove diseased grains and empty grains in the seeds with a concentration of 2.5% salt water. Finally, soak the seeds with a 0.2% boric acid solution for 24 hours.

[0045] Dry and soak the milk vetch seeds, according to the sowing rate of 37.5kg / hm 2 After being mixed with the calcium magnesium phosphate fertilizer and soil miscellaneous fertilizer that application rate is respectively 5kg / mu and 23kg / mu, sow in the above-mentioned paddy field with the thin water layer of 1.5cm thickness. At the late tillering stage of the late rice, a s...

Abstract

The invention relates to a double cropping rice and Chinese milk vetch matched planting method and belongs to the field of crop planting. The planting method comprises the following steps that late rice is transplanted to a rice field from July to August of the first year, planting continues to October to harvest the late rice, and Chinese milk vetch is sowed in the rice field before late rice harvesting; early rice is transplanted to the rice field from April to May of the second year, the Chinese milk vetch is turned and pressed before early rice transplanting, and the early rice is planted to harvesting. By adopting the method, natural resources of double cropping rice fields in winter can be fully utilized through matched planting of the double cropping rice and the Chinese milk vetch, the crop yield is increased, incomes of peasant households are increased, green, efficient and sustainable development of double cropping rice planting is promoted, the input of agricultural chemicals is reduced by forming an annual multi-cropping compound intergrowth planting technology system of the rice field, and the problem that the area of a regional winter fallowing field is large and the agriculture is not reasonably developed in winter is solved.

Description

technical field [0001] The invention relates to the field of crop planting, and in particular to a method for co-planting double-cropping rice and milk vetch. Background technique [0002] As one of the most important double-cropping rice-growing provinces in southern my country, Jiangxi is rich in light, heat and water resources, and most areas are suitable for multi-cropping of rice in winter crops. However, at this stage, the double-cropping rice fields are generally idle in winter, which causes great waste to the local favorable agricultural production conditions. [0003] The Poyang Lake Ecological Economic Zone is an important grain production area in Jiangxi Province. During the construction of the Poyang Lake Ecological Economic Zone, on the premise of maintaining and improving the regional grain production capacity, it is necessary to run through ecological and environmentally friendly production methods to create a green and efficient Poyang Lake ecological econom...
