Intercropping fruit trees with spring wheat, such as the improper use of spring wheat seedling herbicides, will cause phytotoxicity on fruit trees or the lower dicotyledonous crops, which will seriously affect the growth of fruit trees, which may lead to reduced or even no harvest of the lower dicot crops. First, pre-planting technology In general, glyphosate or Gram-free herbicides are not used between fruit trees. Practice has shown that long-term use of glyphosate or Gram-negative herbicides in fruit trees will weaken the growth of fruit trees and cause fruit deficiency. For particularly lush orchards of weeds, we can use once-in-a-life herbicides such as glyphosate or Gramoxone every 3 to 5 years. Second, seedling after interplanting 1. After emergence of spring wheat, herbicides can be used in the weeds at the 2 to 4 leaf stages, which can prevent weeds in the fruit ditch. If too much weeds can be used to increase the amount, general herbicides should not be mixed with foliar fertilizers. 2. Control of dicotyledonous, rapeseed, ash and other dicotyledonous weeds, can currently only be selected tetramethyl sodium chloride water agent, it is strictly prohibited to use 2,4 ~ D butyl ester or superstar, giant addition, green Huanglong and other pesticides. Because 2,4-D-butyl ester has a strong drifting injury to fruit trees, superstars, giant additions, and green-yellow hybrids produce phytotoxicity to interplanted rapeseed, soybean, flax and other dicotyledonous dicotyledonous crops. 3. Control of wild oats, barnyard grass, Setaria and other monocotyledonous weeds can choose to use thrips or spermatophyte, fruit trees will not produce phytotoxicity. 4. In order to improve the efficacy, it is best to use sodium dimethicone sodium water solution alone, such as sodium dimethicone sodium water solution mixed with hummer, and 667 square meters to increase the dosage of humming horses up to 70 grams. 5. When dimethyl tetrachlorohydrin water solution is used alone or mixed with tetrahydrochloride sodium tetrahydrate and thrips, the sprayer must wear anti-fog cover when spraying. It is better to spray from 10 cm away from the sapling and lower the sprayer as far as possible to avoid The liquid is drifted on the seedlings to prevent fruit trees from being infected with liquid medicine. Third, the fruit weeds in the ditch Because of the large space between the plant gaps in the fruit ditch, the water retention after the fruit trees are watered is good. Therefore, the weeds grow quickly and flourish. At least 3 or 4 times a year must be prevented. If reasonable and effective control measures are not taken, the grass will be easily damaged. Seriously affect the growth of fruit trees. Smaller orchards can be controlled by artificial grasses, and chemical grasses can be used for large orchards. Must use high-efficiency, low-toxicity herbicides for rotation. During the flowering period of interplanting spring wheat, herbicides should not be used in the fruit groove to prevent the liquid from drifting onto the spring wheat flower and affecting pollination and reducing yield. No chemical herbicide should be used 20 days before the harvest of spring wheat to prevent the liquid from drifting on the spring wheat, causing excessive pesticide residues in spring wheat intercropping and reducing the quality of spring wheat. 2Ml Refillable Vape Pen,Veiik Disposable Vape Pen,Disposable Vape Stick,Disposable Vape Pens Shenzhen Wanna Technology Co.Ltd , https://www.veiikvape.com
