Essentials of spinach planting techniques in early autumn

Soil selection.

The spinach planted in autumn is not strict to the soil, the cultivation on sandy loam shows early maturity, and it is easy to get high yield in clayey loam.

Apply sufficient base fertilizer.

Spinach has a high absorption rate of nitrogen and potassium, generally applying rotten farm fertilizer 1000kg and ternary compound fertilizer 80kg per mu, and spraying 800times liquid of new high fat film during the whole growth period to improve the utilization rate of fertilizer.

Sow seeds at the right time.

When sowing in early autumn, in order to ensure the whole seedling, the seeds can be soaked with a new high-fat membrane for one day and sowed wet after sprouting. High temperature in autumn, more Rain Water, spinach sowing rate should not be too large, generally sowing dry seeds per mu 1.2-1.5kg. After sowing, in order to ensure the whole seedling and promote the growth of spinach, cover the seed with thin soil, cover the seed with rice straw, or cover it with a shed, reduce the harm of high temperature and rainstorm and direct sunlight, and maintain soil moisture. After two true leaves of spinach were unfolded, the leaf number, leaf weight and leaf area increased rapidly, and the available nitrogen fertilizer was applied twice. Spraying 2-3 times of aqueous solution dominated by instant boron fertilizer in the growth of spinach, combined with spraying vegetable Zhuangxinling, can make the plant stem stout and plant luxuriant, at the same time, it can improve the ability of disaster resistance, reduce the amount of pesticide and chemical fertilizer, reduce residual poison and improve the natural taste of spinach.
