Water spinach is a common vegetable. It has high nutritional value and unique taste. It can protect the intestine very well, so it is liked by many people. Nowadays, many vegetable farmers generally carry out off-season cultivation in order to ensure the efficiency of planting vegetables. For example, greenhouse sheds are planted in many areas. Let's take a look at the cultivation techniques of greenhouse rot. 1, variety selection The water spinach is actually imported from abroad, so we have to choose the varieties suitable for China's climate and various growth conditions for planting. Generally, it is easy to obtain three kinds of large chicken yellow or big bone green or flag leaf for planting in plastic greenhouse. high yield. 2, planting time If the water spinach is planted in the greenhouse, it is mainly cultivated in autumn and winter. In order to get better returns, we usually need to arrange to start planting in October after planting in the greenhouse, so that it can be listed in December, and it can be sold until March of the year. 3. Soil preparation and fertilization The growth of the water spinach is very fast, so the amount of fertilizer is large. In order to get out of the market faster, we should apply enough basic fertilizer in the soil before planting, and it is best to pay attention to the use of various decomposed organic fertilizers when fertilizing. Mixed with fertilization of grass and ash. At the same time, the soil must be fully cultivated, and the planted land must be gathered into a concrete. 4, seed germination Spinach cultivation generally does not scatter seeds in the field, but rather requires the seeds to be first soaked in water. Because the spinach seed coat is thick and hard, it can be germinated directly in the field. If the water control is not good, the seed is easily rotted, so the germination treatment should be carried out first. Note that the seeds can be wrapped in wet gauze for about 20 hours, then germinated in a germination box, and then seeded when the seeds are white. 5, seeding method The spinach can be spread or broadcast in the field. When planting, pay attention to no more than two kilograms of seed per acre. Spreading the seeds, the seeds are covered with a layer of fine soil, which can better promote the seedlings. When planting, about 3cm can be opened, and the distance between the groove and the ditch is about 16cm. After the seeding, some water can be drenched on the soil, which can effectively improve the survival rate of the seedlings of the spinach. 6, field management Water spinach prefers a warm living environment. Therefore, when planting in a greenhouse, it is necessary to do a good job of sealing in time. Try to ensure that the temperature in the shed can reach about 10 degrees, otherwise it will inhibit its growth. The second part is about fertilizer and water control. The spinach has a short growth cycle, so it has to be harvested several times, and it has to be topdressed after each harvest so that sufficient water supply can be maintained. The above is about the introduction of greenhouse vegetable cultivation. If you want high-yield of spinach, you should basically manage these aspects. For the greenhouse, do you have anything to add?
