Introduction of herbicides commonly used in Aquatic vegetable Field
Aquatic vegetables are mainly water chestnut, lotus root, diamond white, Cigu, Ling Ling, water celery and so on. The weeds in aquatic vegetable fields are different from those in dryland vegetable fields. In addition to some wet weeds such as carp intestines in the past few years from drought to water, there are mainly aquatic weeds such as paspalum grass, Hedyotis diffusa, special-shaped sedge, melon bark grass, eye seed, water sedge, flat stem grass and so on, which are very similar to rice field weeds in species. Aquatic vegetables have strong drug resistance, and all kinds of herbicides to control weeds in paddy fields are safe for them. Common herbicides are (used before weeds sprout): 1. 60% butachlor EC. 7500ml per mu of field, add 30kg of water spray. 2. 12% chlorpromazine EC. Use 125 to 150 milliliters per mu and spray 30kg of water. 3. 10% agricultural wettable powder 1525 grams per mu, spray 25 kilograms of water, control broadleaf weeds and annual Cyperaceae weeds, the pesticide is very significant. 4. When mixed with butachlor and other paspalum fungicides (1/2 to 1/3 of the dosage respectively), it can control almost all weeds in aquatic vegetable fields. Note: the whole field should be leveled, and the shallow water layer should be kept for 2-3 days when herbicides are applied.

There are many harm in applying unripe organic fertilizer to fruit trees.
Organic fertilizer, also known as farm fertilizer, is commonly used in fruit production, such as compost, ring manure, stable manure, green manure, cake fertilizer, river mud, poultry manure, human feces and urine, soil manure and so on. Most organic fertilizers need to be decomposed by microorganisms before they can be absorbed by the plant roots, so they are also called "delayed fertilizers" and can be used as base fertilizers.
