Weeding technique field.
Background technique
Sorghum【Sorghum bicolor (L.) Moench】It is the fifth-largest cereal crops in the world, in Africa, Asia, drawing
It plants extensively on the ground such as fourth America.Sorghum is in existing more than 5000 years cultivation histories of China, and in the five, sixties, sorghum is in China
Plantation extensively, is northern main food.Sorghum is wine brewing, makes vinegar primary raw material, and China sorghum cultivated area is 10,000,000 at present
Mu or so, with brewing with based on sorghum.Modern scientific research show tannin in sorghum and resistant starch beneficial to human health, it is right
Obesity, diabetes, hyperlipidemia chronic diseases have dietary function, therefore edible sorghum will be sorghum developing direction.
Sorghum gramineous crop, weeds in field is based on gramineae weed, and habit is identical as sorghum, jowar pair
Herbicide is very sensitive, and sorghum field does not have safe and efficient chemical herbicide so far.Before 2010, sorghum is with family's small area
Based on plantation, manually weeding；In recent years, agricultural planting structure changes, the large-scale planting based on cooperative society, it is few then
Several hundred mus, more mus then up to ten thousand, chemical weed control have become the great difficult problem for restricting sorghum production.Sorghum that is current to produce, using
Field herbicide after seedling has atrazine, dichloro quinolinic acid, dimethyl tetrachloride, and herbicide before seedling stage has prometryn, isopropyl methoxalamine, these are removed
Careless agent is mostly applied on corn, rice.Since resistance of the sorghum to these herbicides is poor, can only low dosage use, but weeding imitate
Fruit is bad；High dose uses, and serious phytotoxicity can occur for sorghum.Meanwhile also there are stringent limitation, otherwise, weeding on spraying time
Effect is bad.Isopropyl methoxalamine is efficient, safe, economic herbicide, in dicotyledonous crops such as soybean, peanut, some vegetables
It is upper to use extensively.Isopropyl methoxalamine and atrazine spray weeding before being blended in Sorghum Seedlings, have a small amount of peasant to use.In arid and semi-arid
Area, jowar field spray isopropyl methoxalamine, and rainfall is encountered before 5 leaf of jowar seedling, and seedling can grow normally；But in moist south
Side, after spraying isopropyl methoxalamine, encounters rainfall, seedling leaf can distort metamorphosis, and serious phytotoxicity, Bu Nengsheng occurs before 5 leaf of jowar seedling
Length leads to death of seedling, causes Severe Reduction.
Current many jowar experts study for sorghum weeding problem, it is intended to novel sorghum herbicide is filtered out, though
Right some new medicaments are tried out in sorghum production, but herbicidal effect is bad.Find the safe and efficient chemistry of sorghum field
