Convolvulus does not require strict soil, but it is advantageous for soils with sufficient water and fertilizer and strong water retention and fertility. The spinach leaves grow rapidly, requiring large amounts of fertilizer and strong fertility. With sufficient fertilizer and water, good quality and high yield can be obtained, but fertilizer and water should be controlled in the planting area, otherwise the flower will not grow. The basic fertilizer of water spinach is soil-based fertilizer and manure, and the dosage is 600-800 kg per 667 square meters. Scientific fertilization can make it grow faster and longer, stems grow green, significantly improve yield and improve quality. Convolvulus is a crop that has been harvested many times. Therefore, in addition to applying basic fertilizer, it is necessary to carry out multiple stages of top dressing in order to obtain high yields. The seedling stage can be applied with 10%-15% of dilute human waste, and the amount of mu is 1000-1500 kg. When the seedlings have 3-4 true leaves, 15-20 kg of compound fertilizer and 2-4 kg of urea are used in combination, and the harvest time is 1 to 5-8 kg (each mu) of compound fertilizer. When the water spinach seedling grows to 5-10cm, it can be topdressed for the first time. When top dressing, topdressing should be carried out with a standard of 500-700kg of organic fertilizer per 667m2. Fertilizer should be diluted first, then fertilize with watering. Fertilize evenly. If there is too much fertilizer in one place, the plants will be burned. The timely and proper harvesting of water spinach is an important measure to win high yields. Seed-breeding waterweed seedlings are 30-40 cm in height, and the first harvest can be carried out when the vegetatively propagated new cane is 30-40 cm in length, and then harvested several times later. When carrying out the first and second harvest, the base of the cane must be left with 2-3 knots in order to facilitate the sprouting of the new shoots after harvest and to promote the development of lateral branches for high yield. After harvesting 3-4 times, the plants should be re-extracted one time. That is, only one or two knots are left at the base of the cane. Therefore, the number of vines is greatly increased. If the vines are too long and the number of sections is too many, the collaterals will be excessive. , resulting in sluggish production, affecting output and quality. At this time, some over-weak and weak branches may be neglected to achieve the purpose of plant regeneration and rejuvenation. Because of the high yield of water spinach, the demand for fertilizer and water is relatively large, and the top dressing is harvested once. If you only focus on harvesting and neglect topdressing, you will gradually weaken the plants, seriously affecting yield and quality. The topdressing fertilizer is mainly concentrated nitrogen fertilizer and then used with certain phosphorus and potassium fertilizers to achieve high yield and good harvest.
