How to grow spinach in early autumn? Detailed explanation of key cultivation techniques

Soil selection.

Spinach planted in autumn has no strict requirements for soil; when cultivated on sandy loam it shows early maturity, while cultivation on clay loam tends to give high yields.

Apply sufficient base fertilizer.

Spinach has a relatively high uptake rate of nitrogen and potassium; generally apply 1000 kg of decomposed farmyard manure and 80 kg of ternary compound fertilizer per mu; at the same time, spray Xinguozhimu film at 800 times dilution throughout the whole growth period to improve fertilizer use efficiency.

Sow at the right time.

When sowing in early autumn, to ensure full stands, the seeds can first be soaked in Xinguozhimu for one day, then sown wet after germination. In autumn the temperature is high and there is more rain, so the sowing rate of spinach should not be too large; generally sow 1.2-1.5 kg of dry seed per mu. After sowing, to ensure a full stand of spinach and promote growth, cover the seed with a thin layer of soil, or cover with rice straw, or set up a shed for shade, to reduce the harm from high temperature and heavy rain and direct sunlight, and to maintain soil moisture. After the two true leaves of spinach unfold, the leaf number, leaf weight and leaf area grow rapidly, so apply quick-acting nitrogen fertilizer 1-2 times. During spinach growth, spray 2-3 times with an aqueous solution mainly of quick-dissolving boron fertilizer, and in combination spray Zhuangjingling for vegetables, which can make the plant stems thick and strong and the plants luxuriant, and at the same time can enhance the ability to resist disasters, reduce the amount of pesticides and chemical fertilizers, lower residual toxins, and improve the natural taste of spinach.
