First, soil selection.
The spinach planted in autumn is not strict with the soil, and the cultivation on the sandy loam soil is precocious, and it is easily cultivated in the clay loam soil.
Second, apply base fertilizer.
Spinach has higher absorption rate of nitrogen and potassium. Generally, the farmyard manure is 1000kg and the compound fertilizer is 80kg. At the same time, the new high fat film is sprayed 800 times at the same time to increase the fertilizer utilization rate.
Third, timely sowing.
In the early autumn sowing, in order to ensure the whole seedlings, the seeds can be soaked with a new high-fat membrane for a day and then sowed in wet sowing. High temperatures in the autumn, rain, spinach sowing amount should not be too large, generally 1.2-1.5kg sowing per acre species. After sowing, in order to ensure that the spinach is full seedlings and promote growth, and thin soil cover species, or covered with straw, or scaffold shelters, reduce heat and rain hazards and direct sunlight, and maintain soil moisture. After two true leaves of spinach were unfolded, the number of leaves, leaf weight, and leaf area increased rapidly, and nitrogen fertilizer was applied 1-2 times. The spinach is sprayed 2-3 times to rapidly dissolve the aqueous solution of boron-based fertilizer, and in combination with the spraying of the strong stem of vegetables, the stems of the plants are stout and the plants are lush, and at the same time, the anti-disaster capacity can be improved, and the amount of pesticide and fertilizer can be reduced. Residues, improve the natural taste of spinach.
