The first is to disinfect the soil. The field where the watermelon is planted can be disinfected with 1 to 2 square meters of 3-5 grams of carbendazim or 100 kilos of lime. (The above two methods are all ploughed after sowing, so that the soil is mixed and the lime cannot be used. Year after year). Insect pests can be used for spotted nests with soil insecticides or field pesticides.
The second is the re-application of base fertilizer. The base fertilizer can be selected from the following formulas: 3,000 kg of farmyard fertilizer, 100 kg of phosphate fertilizer and 40 kg of potassium sulfate; or 3000 kg of chicken and duck dung (after fermentation of fresh manure), 50 kg of phosphate fertilizer, and 30 kg of potassium sulfate.
The third is the field car. After the fertilizer is evenly mixed in the soil, press 2.5-3.5 meters to open the car (bagging ditch). If the intercropping is carried out, the melon road will be 1.3 meters long and other 1.3 meters of other vegetables will be used, so that the amount of base fertilizer used for watermelon melons will be halved. If potassium sulfate is not available, 10 kg of potassium dihydrogen phosphate per acre can be used instead. The effect is better. Then apply the good fertilizer melon road straighten and finely and completely before the planting, do well, the ditch is more than 20 centimeters deep, do a good ditch (the ditch should be 30 centimeters, reach the rain to stop the water, the ditch can dry).
The fourth is weeding with chemical agents. Because of the large area of ​​the watermelon field, manual weeding is very troublesome. After the experiment showed that the soil was sprayed before the film was covered, the following herbicides were effective: trifluralin, durle, gramineous and purslane, tetrabexin, aconite, napropamide, grass and sedge Control efficiency is quite good. Note that acetochlor is used in watermelon fields.
With the development of productivity, the proportion of raw materials produced by industry in the whole raw materials will be greater than that produced by agriculture, and there is a trend to further increase. Vigorously developing raw materials for industrial production is the main direction to solve the problem of raw materials, but under the condition of the level of science and technology, it is mainly used in the production of means of production, daily necessities and clothes, etc., can not replace the food, textile, paper and other industries by agricultural production of raw materials. Therefore, although the proportion of raw materials in the composition of raw materials for agricultural production has a downward trend, the absolute quantity will continue to grow.We have Alkyl Hydroxy Oximido Acid,2-Methyl-2-Butene,Hexadecafluoroheptane,Iminodiacetonitrile,Dibutyl Oxalate.Xi'an Henrikang Biotech Co., Ltd., was established in 2012.
