Water spinach planting technology:
Water leek has two kinds of shallow water planting and deep water floating plant. Shallow water planting is cultivated in shallow paddy fields or shallow ponds. Let the water be drained before planting, soil preparation, weed removal, and cutting. The cuttings are about 20 cm long and are inserted obliquely at a distance of about 26 cm for 2 to 3 knots, and the depth is about 3 cm. After cutting, in order to improve soil temperature and facilitate rooting, the water layer should not be too deep, generally it is suitable to keep 6 cm to 9 cm.
The method of deep-water floating is to weave the leeks at a distance of about 15 cm on the vines or straw ropes of the bun. In order to make the weight of the two sides of the rope equal, the head and tail of the seedling are rotated. The rattan or straw rope is 10 meters long and 3 meters long. The two ends are made into circles and placed on the wooden stakes on the side of the pond. In this way, the seedlings can float up and down as the water surface rises and falls. In order to facilitate management, the arrangement of the vines or straw ropes in the water can be taken in large and small rows. The distance between the two ropes is 1 meter, and the distance between the two ropes is 30 centimeters. Bamboo floating beds can also be used. The bamboo floating bed is thought to use bamboo material, using large bamboo to form a frame. The smaller bamboo forms a bamboo row with a gap along the frame, and then is tied at a certain distance with a bamboo tube with a small water hole. On bamboo, it is used to cultivate water spinach while protecting part of the roots of plants.
Regardless of the depth of the water level, the shelf on the water surface is used as a carrier for the colonization of the water spine. After the cultivation of the spinach is completed, the bamboo is discharged into the water, and the water is spliced ​​and assembled to connect the floating island. The standard is that the bamboo floating bed floating on the water surface cannot be blown by the wind. Chaos. The assembled floating bed can float up and down with the change of the water level. For the convenience of management and picking, the boat can be used to walk through it, and a certain distance is reserved in the open water body for the production operation. It can also be used as a scenic passage for tourists to visit. The floating bed has the characteristics of no secondary pollution, low cost and easy availability, simple processing and repeated use.
The floating bed can also be used with a fishing net. The two nets are fixed on both sides of the river. A certain number of floats are fixed on the net to keep the whole net on the water surface. The next step is to fix the bamboo tube or nursery raft on the net at a certain distance. The method of saving labor is to put a straw curtain on the fishing net (or the bamboo floating bed), and then the transplanted hollow vegetable seedlings can be directly placed on the straw curtain, and the transplanted roots of the seedlings should have some soil.
When planting seedlings, use land, add base fertilizer and a small amount of compound fertilizer, spread or hole sowing, the seed is covered with a thin layer of soil, sprinkle water to be seedling, in summer, when the sun is strong, the seedbed is shaded, the soil moisture is maintained, and the plant spacing is 7 and 8 About three centimeters, 3 to 4 seeds per hole. Calculated by the actual planting area of ​​the water surface, the seeds per acre are about 35 kg. The spinach leaves from the cotyledons to the seedling stage of 4-5 leaves, the suitable temperature is 20-25 °C. It can be combined with the seedlings at a plant height of 18-21 cm, and the row spacing is 12-15 cm. In the summer, about 30 °C can be harvested once a week. When harvesting, be careful to leave the young shoots. The next time you harvest the spinach, the sprouts grow out. The growth height can be harvested at 18-21 cm. . The transplanting spacing is also preferably 12-15 cm. The suitable temperature for stem and leaf growth period is 25-35 °C. The removal of seedlings is not strict with the light conditions. It is best to choose continuous weather and good weather for the teething. Weeds are relatively rare when cultivated on the surface. The original weeds in the river water are grown in water. There are few water plants exposed to the water surface and compete with the water surface for the water surface space and sunlight. The yield of the water spinach depends on the number of picking and the weight of each picking, and also depends on the richness and richness of the river water. The increase in the number of pickings and the amount of harvesting each time mainly depend on three key links: “early planting, multi-fertilization, and pickingâ€. The cultivation of water spinach on the surface of the water must artificially increase the yield and growth rate and can be sprayed with foliar nutrient fertilizer. Spray once every harvest.
The management of water leek is simple. In the relatively fertile water quality, the plants grow well and generally do not fertilize. In the stagnant water shortage, fertilization should be applied. When the water is high, the temperature is high, and it is harvested once every 10 to 15 days. After the weather is cool, it is harvested once every 20 days. The harvesting method is the same as the drought. The leeks planted in floating water are tender and tender, but the yield is not high due to inconvenient fertilization. In the late growth stage, the stems and leaves are senescent, and the autumn leafy vegetables have many types, which can be allowed to grow and used as green feed. Harvested before the frost falls.
