Cress is also a wild celery. It is a perennial plant with a fragrant flavor and good taste. It is loved by people. Artificial cultivation uses the characteristics of cress like water and can grow in water, and starts the method of water cultivation in greenhouses. 1. Greenhouse setting Summer is hot and affects growth, so the greenhouse used in summer planting is actually a sunshade cooling facility, mainly to cool down and make celery grow better. Choose a planting field and build a greenhouse, which can be built directly in the paddy field. Field tillage, fertilization and mixing, irrigation, rake leveling can be used as a reserve. 2. Planting It can be planted twice in summer, and the first time the old plant is directly harvested, the young branches and leaves are cut off, and the old stem is directly cut into small pieces, and the cuttings are cut directly, and the cutting distance is about a few centimeters. New plants can be produced in about a month. Can be sold directly. The second time to sow, sow directly on the border surface, cover with straw, water and moisturize, and continue to cultivate after sprouting. 3. Greenhouse management It is required that the shed film with a shading rate of 60% cannot be too high, and the growth of seedlings cannot be photosynthesized; it cannot be too low, and the shading effect is not good, which will still affect growth. Usually when the sun is at its maximum, spray water on the shed to cool down. Shade nets should be built on the shed. Generally, the membrane should be ventilated at night, and ventilation should be introduced to avoid too much carbon dioxide. 4. Fertilization After the base fertilizer is over, it can be top-dressed when there are 5 leaves, and fertilize 1,000 acres of farm fertilizer on one acre. No poultry fat. Do not pour the fertilizer on the leaves. High fertilizer concentration can easily burn the leaves. When fertilizing, put some water into the soil easily, and irrigate it two days later, to avoid too high concentration, and to maintain the water demand of the root system. Later, observe the growth and continue to top dress. 5. Irrigation Cress planting, mainly in the water environment, requires a clear water source, can be kept dry and wet when sowing, easy to germinate, and will not wash away the seeds. When the seeds germinate and the seedlings are too long to wash away, they can maintain a 5 cm water layer. When the growth height reaches more than 20 cm, the water depth can reach 15 cm deep. High temperature and deep water during the day, can be cultured in shallow water at night. Disclaimer: Some articles of this website are transferred from the Internet.
