You can grow vegetables in your own basic farmland, but only in areas around big cities.

Other places can only grow food.

For details, please ask the local Agriculture and Rural Affairs Bureau.

Common vegetables include: spinach, lettuce, lettuce, water spinach, etc.

Spinach cultivation technology

Sowing time

Spring spinach can be sown when the temperature rises above 5°C after the beginning of spring. March is the suitable time for sowing. Summer spinach is sown in stages from May to July, autumn spinach is sown from August to September, and winter spinach is sown from mid-October to early November. Spinach usually germinates in 2 to 3 days after sowing.

Soil preparation and bordering

Choose loose and fertile soil with good water and fertilizer retention and good drainage and irrigation conditions. When preparing the land, apply 4,000 kilograms of decomposed organic fertilizer and 40 kilograms of superphosphate per acre. The soil should be leveled and finely leveled. It is advisable to make a sorghum border in winter and spring, and a flat border in summer and autumn. The width of the border should be 1.2 to 1.5 meters.

Sowing and raising seedlings

Spinach fields generally use broadcast seeding. For sowing in summer and autumn, one week before sowing, soak the seeds in water for 12 hours, place them in a well or store them in a refrigerator or freezer at about 4°C for 24 hours, and then germinate at 20 to 25°C. After 3 to 5 days Sow seeds after germination. Dry or wet seeds can be sown in winter and spring. Sow 3 to 3.5 kg per mu.

Pour enough water on the border surface before sowing. Use a rake to lightly rake the topsoil so that the seeds can be sown into the soil. Cover the border surface with a layer of plant ash.

After sowing in summer and autumn, cover with straw or use a small shed to cover the sunshade net to prevent erosion by high temperature and heavy rain. Keep the soil warm and moist at all times, and the seedlings can be planted in 6 to 7 days. If the temperature is low during winter sowing, cover the border with plastic film or a sunshade net to keep the seedlings warm, and remove them after emergence. ?

Field management

After the true leaves appear on spinach in autumn, pour farmyard fertilizer and water once; after 2 true leaves, combine with thinning, weeding, top dressing first light and then thick, apply more in the early stage Farmhouse fertilizer and water; topdressing 2 to 3 times during the peak growth period, 5 to 10 kilograms of urea per acre.

Keep the soil moist after winter spinach is sown. When there are 3 to 4 true leaves, control water appropriately to facilitate overwintering. When there are 2 to 3 true leaves, the distance between seedlings is 3 to 4 cm. Topdress water and fertilizer according to the seedling condition and weather, mainly farmyard fertilizer and water. In frost, ice and snow weather, it should be covered with plastic film and sunshade net for insulation, or it can be covered with a small shed. After spring begins, choose a sunny day to apply farmyard fertilizer and water to prevent early bolting.

Spring spinach should be covered with plastic film for heat preservation in the early stage. It can be covered directly on the border surface. After the seedlings emerge, remove the film or cover it with a small shed. See more light, refine the seedlings more, and see the seedlings in a timely manner. When applying fertilizer and water, use farmyard manure lightly and frequently in the early stage. In the later stage, quick-acting nitrogen fertilizer should be applied especially 15 days before harvest.

After summer spinach emerges, it is still necessary to cover it with a sunshade net. If it is sunny, cover it and uncover it if it is shaded. Cover it late and uncover it early to facilitate cooling and heat preservation. Watering during the seedling stage should be done with light water in the morning or evening. After 2 to 3 true leaves, apply two quick-acting nitrogen fertilizers. Water after each application of fertilizer to promote growth.
