Embodiment 1
[0029] Present embodiment provides a kind of cultivation method of alfalfa and wheat intercropping under apricot and plum grove in oasis-desert transition zone, comprising the following steps:
[0030](1) Soil preparation: Take 25 points in the oasis-desert transition zone to evaluate the soil organic matter. The evaluation results show that the organic matter content is 3.5g / kg, the alkaline nitrogen is 15.9g / kg, and the available phosphorus is 8.32g / kg. Potassium is 80g / kg, pH is 8.35, the evaluation results show that the soil organic matter is extremely deficient, alkaline nitrogen, available phosphorus, and available potassium are all extremely deficient, and the soil is alkaline. Therefore, 4800kg / mu of organic fertilizer, 130kg / mu of oil residue, 38kg / mu of heavy superphosphate and 20kg / mu of potassium sulfate should be applied in the middle and late August to increase the content of soil organic matter, available phosphorus and available potassium. Then use a power rota...
Embodiment 2
[0039] Present embodiment provides a kind of cultivation method of alfalfa and wheat intercropping under apricot and plum grove in oasis-desert transition zone, comprising the following steps:
[0040] (1) Soil preparation: Take 25 points in the oasis-desert transition zone to evaluate the soil organic matter. The evaluation results show that the organic matter content is 3.7g / kg, the alkaline nitrogen is 16.3g / kg, and the available phosphorus is 8.71g / kg. Potassium is 86g / kg, pH is 8.39, the evaluation results show that the soil organic matter is extremely deficient, alkaline nitrogen, available phosphorus, and available potassium are all extremely deficient, and the soil is alkaline. Therefore, in the middle and late August, 5200kg / mu of organic fertilizer, 140kg / mu of oil residue, 42kg / mu of heavy superphosphate and 35kg / mu of potassium sulfate should be applied to increase the content of soil organic matter, available phosphorus and available potassium. Then use the power ...
