Embodiment 1
[0037] The high-efficiency water-saving technology of dry-sowing and wet-out shallow-buried drip irrigation, water and fertilizer integration of Astragalus membranaceus, specifically includes the following steps:
[0038] Step 1. Autumn plowing: After the previous crops are harvested, apply 1000-1500 kg of manure per mu, and carry out deep plowing and leveling;
[0039] Step 2, sowing: on the eve of sowing in the spring of the second year, spray herbicides, and then directly sow Astragalus on dry land after being suppressed by harrowing;
[0040] Step 3. Fertilizer: Dig a pit on the side of the Astragalus membranaceus sowing, apply fertilizer mainly composed of phosphorus, combined with nitrogen and potassium to the pit, and cover the pit with soil after the fertilization is completed;
[0041] Step 4. Drip irrigation belt laying: After the sowing is completed, a 3cm deep drip irrigation belt is shallowly buried on the side of the Astragalus sowing;
[0042] Step 5. Drip irri...
Embodiment 2
[0044] This embodiment is an improvement of the previous embodiment, and the dry sowing of Astragalus membranaceus is wet out, and the shallow buried drip irrigation water and fertilizer integration high-efficiency water-saving technology specifically includes the following steps:
[0045] Step 1. Autumn plowing: After the previous crops are harvested, apply 1000-1500 kg of manure per mu. Specifically, when applying sheep manure, add pig manure or cow manure, and when applying human manure, it should be mixed with coarse organic fertilizer and phosphorus, Potassium fertilizer, it needs to be explained that long-term application of human excrement and urine will cause soil compaction, it cannot be applied continuously, and it should be used at intervals for deep plowing and leveling. 40cm;
[0046] Step 2. Sowing: On the eve of sowing in the spring of the second year, spray herbicides in strict accordance with the dosage, and then directly sow Astragalus on the dry ground after...
