Embodiment Construction
[0014] The green manure returning method of the embodiment of the present invention comprises:
[0015] Step 1: Sow a variety of green manures according to the first seeding rate.
[0016] It should be noted that the types of green manures can be hairy leaves, peas and rapeseed, and of course other types of green manures. The planting bar spacing of green manure is 10cm-15cm, for example, the bar spacing is 10cm, 12cm, 13cm, 14cm, 15cm.
[0017] For example, the first seeding rate of saffron is 180kgha -1 , the first seeding rate of arrow peas is 195kgha -1 , the first seeding rate of rapeseed is 10kgha -1 .
[0018] Preferably, 8-10 g·kg can be added to the green manure before sowing the green manure in step 1 on the land where green manure has never been planted. -1 Seed dressing treatment of green manure with bacterial agent.
[0019] Step 2: irrigate and fertilize each green manure in step 1.
[0020] For example, the green manure in steps 2 and 5 can be irrigated a...

The invention relates to the technical field of agricultural planting, in particular to a green manure returning method which comprises the steps that according to the first sowing amount, multiple green manure is sown in a shallowly-rotating and strip-sowing mode; irrigating and fertilizing each kind of green manure in the step 1; according to the soil water storage capacity and the soil nitrogen content, any one of the multiple green manure in the first step is selected as target green manure, and the green manure returning amount, the smashing degree and the returning depth of the target green manure are selected; detecting soil biomass, and determining a second seeding rate according to a formula 1; according to the target green manure in the step 3 and the second sowing amount in the step 4, the green manure is sown in a shallow rotary drill sowing mode, and irrigation and fertilization are conducted on the green manure; crushing the green manure in the step 5 according to the returning amount and crushing degree of the green manure in the step 3, and covering the ground surface with the crushed green manure; the green manure covering the earth surface in the step 6 is turned over and returned to the field according to the returning depth in the step 3 before main crops are sown in the next year. According to the method for returning the green manure to the field, the accuracy of returning the green manure to the field can be improved.
Description
technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a method for returning green manure to the field. Background technique [0002] As a clean and ecological organic fertilizer source, green manure can continuously improve the quality of cultivated land, ensure stable and high yield of crops, and contain huge ecological and economic potential. Green manure can increase nitrogen fixation and mineralization in soil, improve soil fertility and nitrogen use efficiency. In the related art, the determination of the amount of green manure sowing and the amount of returning to the field mainly relies on experience, and the inaccuracy of the amount of sowing and returning of the green manure will easily cause adverse effects on soil fertility and subsequent crop yield. SUMMARY OF THE INVENTION [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. To thi...
