1. Variety selection

two。 Cultivation environment

The planting pot is placed on the balcony where the light is better, but it can prevent the sun from being exposed to the sun for a long time.

3. Cultivation season

Spinach is a cold-tolerant vegetable, which can be sowed from late August to early April of the following year, and the quality of cultivation in autumn and winter is better.

4. Sowing seeds

(1) pre-broadcast preparation

Substrate treatment before sowing: spinach should choose pollution-free substrate. 1-2 days before planting, keep the original state of the basin matrix unturned, wet the matrix to the bottom with clean water, and make the matrix moist. Substrate treatment and sowing can also be carried out at the same time, but the substrate is too wet to cause rotten seeds and too dry to cause irregular germination and emergence.

(2) sowing time: from September to March of the following year, sowing mainly by direct seeding. Soaking seeds to accelerate germination and sowing seeds.

(3) sowing technique: after the basin soil is watered, the seeds are sown on the soil surface, covering about 1 cm, slightly compacted and watered. Keep the soil moist before germination, or cover a layer of plastic film after sowing to keep the substrate moist, which is conducive to seedling emergence, and remove the film in time when 50% of the seedlings emerge.

5. Administration and Management

(1) fertilization management: the substrate carries certain nutrients, which can be irrigated with organic fertilizer fermented liquid made from rice panning water, pericarp, kitchen residue and other materials commonly used in daily life.

(2) Water management: watering once every 5-7 days in winter and spring to keep the soil moist and avoid being too dry and too wet. Avoid watering at noon in the hot season.
