How do you grow hornwort so it grows best?
Hornwort belongs to the algae plants, grows for many years in the still water of small lakes, has a certain medicinal value, can be used as feed for pigs, fish and poultry, and also has certain harms, but hornwort is very difficult to cultivate, so let us take a look below at how best to grow hornwort!
How to grow hornwort
1. Hornwort planting should be dense rather than sparse. If a grower wants to achieve high yields, with insufficient basic seedlings, the yield will be hard to raise. Generally speaking, to cultivate this kind of aquatic plant, it is appropriate to transplant 200 clumps per mu of water area.
2. During cultivation, the fertilizer should be rich rather than lean. If you choose those barren water surfaces that cannot be used to raise fish or shrimp for planting hornwort, these relatively poor-quality water areas should have the water moss and other weeds removed before planting, then apply 25 kg of superphosphate per mu of water surface as base fertilizer, and apply little nitrogen fertilizer to prevent green algae from taking over the water surface. Then plant the hornwort.
3. The water area for planting hornwort must not be too deep, and generally keeping it within a range of 1 m is most suitable. Because if the water is too deep, the stems will be coarse and the leaves will be few, greatly reducing the yield, and the utilization rate of the aquatic plant will also decrease, thereby lowering the commercial value of growing hornwort.
In addition, under normal circumstances, from planting hornwort to the first harvest is generally 50 days. During harvest, note that you need to lift the stick and shake it, turn it 4-5 turns in the water, then hold the stick horizontally and lift it up with both hands. The time for the second harvest should be 30 days later, and the third harvest only needs an interval of a few days.
What are the harms of hornwort
1. Harm: Hornwort is distributed throughout China, especially in rice fields where the water is rich in organic matter, the water layer is relatively deep, and the fields are submerged for a long time, where it is distributed more and the harm is more serious. In addition, it is also distributed in still-water ponds, lakes and ditches. Because hornwort has a very strong ability to absorb nitrogen and at the same time lowers the water temperature, it seriously affects rice tillering and growth and development.
2. Control: Prevention and elimination should adopt a method combining agronomic measures and chemical weeding.
① Agronomic measures mainly include: first, establishing a rice production environment with level land, smooth ditches, good water retention and free irrigation; second, combining seed treatment to remove weed seeds, and combining plowing and land preparation to eliminate weed seeds on the soil surface; third, implementing regular rotation of paddy and dryland to reduce the occurrence of weeds; fourth, improving sowing quality so that a single sowing gives full seedlings, using seedlings to suppress weeds.
② For chemical weeding, most places adopt a one-time sealing and killing method, that is, within 1-3 days after sowing (bud forcing), use 60 grams of 40% “Zhiboqing” wettable powder per mu, mix with 40-50 kg of water, and spray evenly; keep the field surface moist when applying the pesticide. After 3 days, resume normal irrigation and field management. After chemical elimination, if there is still a certain amount of weeds later, targeted methods can be adopted for supplementary elimination.
