Embodiment 1
[0030] 1. Selection of alfalfa varieties:
[0031] To plant alfalfa on the fertile land of Xinhua breeding cattle field in Tongyu County, Jilin Province, the Gongnong No. 1 alfalfa variety with higher yield should be selected;
[0032] 2. Plot selection
[0033] The land for planting alfalfa in the Xinhua Breeding Cattle Farm of Tongyu County, Jilin Province has a relatively high terrain, flat, well-drained, deep soil layer, a pH value of 8.0, and a total soil salt content of less than 0.15%. + The content is 0.05g / kg, and the soil conductivity is 152us / cm;
[0034] 3. Weeding and Fertilization
[0035] After plot selection, use glyphosate to kill weeds, and 14 days after weeding, carry out soil cultivation;
[0036] Fertilization is one-time application of all fertilizers before soil plowing. The fertilizer is mixed with diammonium phosphate compound fertilizer, superphosphate and potassium chloride. The amount of fertilizer applied is 45kg per hectare of N, P 2 o5 180kg,...
Embodiment 2
[0046] 1. Selection of alfalfa varieties:
[0047] In Changling County, Jilin Province, alfalfa is planted in the land with thin soil fertility and heavy salinity, and the Aohan alfalfa variety with low yield, strong salt-alkali tolerance and low price is selected;
[0048] 2. Plot selection
[0049] In Changling County, Jilin Province, the alfalfa planting plots are flat, well-drained, and the soil layer is deep. The soil pH value is 8.6, and the total soil salt content is less than 0.3%. + The content is 0.20g / kg, and the soil conductivity is below 300us / cm;

[0051] After the plot is selected, glyphosate is used to kill weeds, and 12 days after weeding, the soil is plowed; fertilization is one-time application of all fertilizers before soil plowing, and the fertilizers are diammonium phosphate compound fertilizer, superphosphate and potassium chloride. Proportion, the amount of fertilizer applied is 30kg of N and P per hectare. 2 o ...
Embodiment 3
[0061] 1. Selection of alfalfa varieties:
[0062] Alfalfa is planted in Kezuozhong Banner, Inner Mongolia Autonomous Region, and the selected variety is Grassland No. 1 alfalfa;
[0063] 2. Plot selection
[0064] The land for alfalfa planting in Kezuozhong Banner, Inner Mongolia Autonomous Region has a relatively high, flat, and deep soil layer. The soil is sandy loam with a pH value of 7.5. The total salt content of the soil is less than 0.15%, and the Na content of the soil is + The content is 0.08g / kg, and the soil conductivity is 98us / cm;
[0065] 3. Weeding and Fertilization
[0066] After the plot is selected, use the herbicide of agricultural grass to kill the weeds. After 15 days of weeding, the soil is plowed; the fertilizer is applied to all the fertilizers before the soil plowing. The fertilizer is diammonium phosphate compound fertilizer, superphosphate and chlorine. Potassium is used for proportioning, and the amount of fertilizer applied is 35kg per hectare ...
