Embodiment 1

[0025] The land for water shield cultivation was selected in Maqian, Lichuan City, which has always been used for agriculture, without industrial pollution, good water source conditions, relatively complete vegetation preservation, and less damage. After selecting the land for cultivation, first disinfect it with 50 jin / mu of lime, then renovate the embankment to a height of 50 cm, and inject water so that the water storage height is about 50 cm.

[0026] The selected seedlings were sterilized with 0.2 mg / L chlorine dioxide disinfection powder for 24 hours and completely soaked, and planted in early spring. The amount of seedlings was 30 catties / mu, and the water level was kept at 40 cm deep after termination.

[0027] During the planting process, biological pesticides are used to prevent pests and diseases.

[0028] After the harvest of water shield in spring and summer, apply 1 / 4 concentration of balance solution, 50L / mu, to the thin seedling field. After harvesting Braseni...

Abstract

The invention belongs to the technical field of crop cultivation, and discloses a Brasenia schreberi cultivation method which includes the steps: Brasenia schreberi cultivation land selection; seedling selection; disinfecting and planting; pest control; balanced solution applying after harvesting. According to the method, the Brasenia schreberi cultivation land is strictly selected, seedlings arescreened, field management is implemented, so that Brasenia schreberi grows in water environments without any pollution, application of a lot of fertilizers is avoided, and the yield of the Brasenia schreberi and economic benefits are improved when organic health of the Brasenia schreberi is ensured.

Description

technical field [0001] The invention relates to the technical field of crop cultivation, in particular to a healthy and efficient cultivation method for water shield. Background technique [0002] Water shield is a perennial aquatic perennial herb with edible young leaves, which is one of the precious vegetables. The cuticle of mucus hairs on the surface of water shield is very thin, and it secretes polysaccharides and other substances to prevent water erosion and germ invasion. After the mucus hairs age, only the cell membrane protects the internal structure of the plant, so it is very sensitive to changes in ions in the external environment. [0003] The current technology of cultivating water shields randomly spreads the vegetative propagules into the paddy fields and fertilizes randomly, resulting in uneven growth, disordered quality, and even seedling degradation of water shields; and the existing cultivation technology can only be harvested in the autumn of the second ...
