Embodiment 1

[0024] Select plots in the Gaotai area of ​​Gansu Province, and use Gannong 5 to conduct experiments. The alfalfa seeds were planted in holes covered with film in April in the spring, and the thickness of the film was 10 μm. The alfalfa seeds were harvested in early August, and the autumn harvest was carried out at the end of September. After the autumn harvest, use dry cow dung, hay stalk, grass powder to mix and make organic fertilizer to cover, cover thickness 0.5cm, described dry cow dung, hay stalk, grass powder are pulverized, and the particle diameter of pulverizing is 3cm, dry cow dung, hay stalk , Moisture content in grass powder is 40%. The dry cow dung, hay stalks and grass powder are mixed in a weight ratio of 1:2:1. Irrigate once in mid-November before winter, water volume per mu ≥ 80m 3 . Overwintering survival rate of 96%.

Embodiment 2

[0026] Select plots in the Altay area of ​​Xinjiang, and use Gannon 5 to conduct experiments. The alfalfa seeds were planted in holes covered with film in April in the spring, and the thickness of the film was 10 μm. The alfalfa seeds were harvested in early August, and the autumn harvest was carried out at the end of September. After the autumn harvest, use dry cow dung, hay stalk, grass powder to mix and make organic fertilizer to cover, cover thickness 1cm, described dry cow dung, hay stalk, grass powder are pulverized, and the particle diameter of pulverizing is 3.5cm, dry cow dung, hay stalk , Moisture content in grass powder is 30%. The dry cow dung, hay stalks and grass powder are mixed in a weight ratio of 1:2:1. Irrigate once in mid-November before winter, water volume per mu ≥ 90m 3 . Overwintering survival rate of 95%.

Embodiment 3

[0028] Select plots in the Zhongwei area of ​​Ningxia, and use Gannon 5 to conduct experiments. The alfalfa seeds were planted in holes covered with film in April in the spring, and the thickness of the film was 15 μm. The alfalfa seeds were harvested in early August, and the alfalfa was harvested in autumn in early October. After the autumn harvest, use dry cow dung, hay stalk, grass powder to mix and make organic fertilizer covering, cover thickness 1cm, described dry cow dung, hay stalk, grass powder are pulverized, and the particle diameter of pulverizing is 4cm, dry cow dung, hay stalk, The moisture content in grass powder is 30%. The dry cow dung, hay stalks and grass powder are mixed in a weight ratio of 1:2:1. Irrigate once in mid-November before winter, water volume per mu ≥ 90m 3 . Overwintering survival rate is over 98%.

Abstract

The invention relates to the technical field of plant seed planting, in particular to a method for safe wintering of non-autumn dormancy level alfalfa. Alfalfa seeds are planted in a plastic mulching and hole sowing mode in spring, covering of organic fertilizer prepared by mixing dry cow dung, dry straw and grass meal is conducted after autumn harvesting, and pre-winter irrigation is conducted. Dry cow dung, dry straw and grass meal are smashed to obtain particles with diameters smaller than or equal to 3 cm, and the water content in dry cow dung, dry straw and grass meal is smaller than or equal to 40%. The dry cow dung, dry straw and grass meal are mixed according to the weight ratio of 1:2:1, the wintering survival rate in the next spring can be 95% or above, and a non-autumn dormancy level alfalfa seed breeding field is successfully built.

Description

technical field [0001] The invention relates to the technical field of planting seeds, in particular to a method for safely overwintering non-fall dormancy grade alfalfa. Background technique [0002] Alfalfa is an important forage crop in my country. China has a large area of ​​alfalfa land, and there is a great demand for seed production. The study found that the fall dormancy grade of alfalfa is related to the cold wintering tolerance. In northern China, especially in the areas north of 35 degrees north latitude, non-fall dormancy grade alfalfa cannot survive the winter. The specific varieties are fall dormancy grade 7-11 or 7-9. The overwintering survival rate is low, and it cannot be used for seed production or planting grass. In the second year, the emergence of seedlings is irregular, the seedlings are weak, and the quality of seedlings is poor, which seriously affects the yield and quality of alfalfa seeds. Therefore, non-fall dormancy grade alfalfa should only be ...
