Embodiment 1

[0037] The cold-resistant and overwintering cultivation method of winter green manure Er Yuelan in the Beijing-Tianjin-Hebei area comprises the following steps:

[0038] (1) Choose cold-resistant Eryuelan varieties: Eryuelan is relatively strong in overwintering. Select the cultivated species in North China or the wild species in Northeast China with relatively strong cold tolerance.

[0039] (2) Fertilizer application for strong seedlings and cold resistance: Potassium sulfate and potassium carbonate or potassium humate fertilizers are applied in the sowing ditch at a ratio of 6:4, the main function is to promote seed germination and improve the cold resistance of seedlings.

[0040] (3) Moisture-preserving and cold-proof sowing: after sowing the Er Yuelan seeds, cover the soil with a thickness of 1~2cm, suppress it, and properly irrigate to keep it moist until the seedlings emerge; the sowing rate is 45kg per hectare; mix 10% rye seeds in the Er Yue Orchid seeds for mixed b...

Embodiment 2

[0048] The cold-resistant and overwintering cultivation method of the Beijing-Tianjin-Hebei region winter green manure vetch, comprises the following steps:

[0049] (1) Choose cold-resistant vetch varieties: In the Beijing-Tianjin-Hebei region, it is best to choose cultivars in Northwest China and North China, mainly including Turkmen vetch, Mongolian vetch, and Qinghai vetch.

[0050] (2) Fertilizer application for strong seedlings and cold resistance: Potassium sulfate and potassium carbonate or potassium humate fertilizers are applied in the sowing ditch at a ratio of 6:4, the main function is to promote seed germination and improve the cold resistance of seedlings.

[0051] (3) Moisture-preserving and cold-proof sowing: cover 2-3cm thick soil after sowing the vetch seeds, suppress them, and properly irrigate to keep them moist until seedlings emerge; increase the sowing rate to 75kg per hectare; mix 20%% rye seeds in the green manure seeds for mixed sowing . The main fun...

Abstract

The invention discloses a culturing method of resisting coldness and overwintering for winter green manure crops in Beijing-Tianjin-Hebei regions. The method comprises the steps that winter green manure crops of the variety capable of resisting and tolerating coldness are selected; before September 25th, land is levelled, seeds are sowed in line, a mixed potassium sulphate and potassium carbonatefertilizer or a potassium humate fertilizer is applied to promote seed germination and seedling growing, a coldness resistance fertilizer is applied, and after pressing, the seeds are appropriately watered to keep wet until seedlings emerge. In the seedling period of the winter green manure crops, a straw fertilizer is applied to resist coldness, keep warmth and provide nutrition. The seedlings are watered by frozen water, which is beneficial for overwintering of the green manure crops. After the winter green manure crops turn green, urea is rapidly dressed to promote early and rapid growing of the seedlings. The culturing method of resisting coldness and overwintering for the winter green manure crops is beneficial for safe overwintering of the winter green manure crops, coldness resistance, warmth keeping, and increasing of the overwintering rate, the reviving rate, the covering rate and the biological yield, therefore carbon is stored, nitrogen is fixed, the fertility of soil is improved, and dust raising is inhibited, using of a later crop fertilizer is reduced, and a pure organic fertilizer replaces a chemical fertilizer; energy conservation and emission reduction are achieved, the environment is beautified, and the scientific planting method is provided for healthy crop rotation and fallow planting of the Beijing-Tianjin-Hebei regions.

Description

technical field [0001] The invention relates to a cultivation method for increasing the survival rate of overwintering green manure crops in the Beijing-Tianjin-Hebei region, in particular to a cold-resistant and overwintering cultivation method for green manure crops in the Beijing-Tianjin-Hebei region. Background technique [0002] The Beijing-Tianjin-Hebei region is gradually implementing the planting system of crop rotation and fallow. In areas without surface water irrigation and deep groundwater overexploitation, crops that consume large amounts of water will be left fallow; in areas where ecological functions are degraded and available water resources are scarce, and other farmlands that are not suitable for continuous farming, green manure will be planted for one season. field. Through the fallow planting of green manure returning to the field and the rotation of grain and beans, the combination of planting and breeding can improve soil fertility, reduce irrigation ...
