Spinach is a drought-tolerant crop, so it is not so easy to grow spinach in the hot summer. The price of spinach in the summer is also expensive. Many farmers want to seize this business opportunity. Let's learn together. Learn about the key points of planting summer spinach. Seeding Usually, summer spinach is usually sown in June and July. Before sowing, you should soak the seeds in water for about 12 hours, then put them in cold water of four degrees Celsius for ten to twenty-four hours. Finally, put the germination in the environment of fifteen to twenty degrees, generally wait for about three or four days, the seeds can be sown after being white. The seeding method is mostly spread, and the water is first planted and then planted. The density of sowing should not be too dense. 2. Site preparation The soil for planting summer spinach is excellent in drainage, soil fertility and fertility, and fertilization is mainly based on nitrogen fertilizer. When the soil is prepared, about 2,000 kilograms of farmyard manure can be applied per acre, and NPK fertilizer is 30 to 40 kilograms. It is also necessary to make the land fine and flat, and make it into a sorghum or a flat. 3. Field management Summer spinach cultivation usually most vegetable farmers choose to cover the sunshade net, the purpose is to cool and moisturize, creating environmental conditions for the high-yield planting of summer spinach. After emergence, the method of sprinkling irrigation is used, and small water is poured. After the leaves grow 2-3 pieces, the nitrogen fertilizer is applied twice, and the phosphorus and potassium fertilizers are properly matched. After fertilization, watering should be added to promote the growth of the stems and leaves of the spinach, so that the spinach produced has high economic value. 4. Timely harvest The sunshade net will be removed a week or so before picking. The temperature in summer is very high, and spinach is also easy to twitch. Generally, about 30 days after sowing, when the spinach plant grows to about 20 cm, it can be harvested and listed, and the spinach can be kept fresh. In general, the cultivation of spinach in summer is mainly to do field management work, pest control work, etc. As long as the management work in the week is done, high yield is relatively easy.
