Spinach is planted in early autumn, with a growth period of about 30-40 days, a short period of time, and a quick market for vegetables, which can meet the market's demand for autumn mussels and achieve higher economic benefits.
1. 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. The acid resistance is weak, the suitable soil pH is 5.5-7, and the soil pH is below 5.5 or 8 and the growth is poor.
2, sowing time. Planting will take place around August 20th and will be available around the end of September. The main choice of heat-resistant high-yield garden spinach varieties, such as all-round spinach.
3, apply enough base fertilizer. The absorption rate of nitrogen and potassium in spinach is relatively high. In general, 1,000 kg of rotten farmyard manure and 80 kg of ternary compound fertilizer are used in Mushi; at the same time, the soil moisture in the whole growing season must be 70-80% of the field water holding capacity.
4, timely sowing. Live, box width 2-1.5m, into turtle shape, 2-3 times uniform sowing, early autumn sowing, in order to ensure the whole seedlings, seeds can be used first 15-20 °C flooding day, germination, 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.
