Herbicides suitable for use in orchards
The pre-emergence herbicide soil treatment herbicide, weeds sprout 1-3 leaf stage, spray carefully on the entire garden again. One medication control does not produce grass throughout the year. Pay attention to soil moisture, humidity and good effect, increase the amount of water in the drought, a bag of 20 grams per mu. Over the past five years, Jincheng City, Shanxi Province has popularized and applied fruit farmers, and it has been a good one.
Farmers Music -747 United States imports of the original drug, inactivated within the suction stem herbicides. In the weedy growing season, a single spray was killed. Generally, weeds are packed in barrels, and it is difficult for perennial weeds to remove 4-5 bags per mu. Yellowing began 4-5 days after spraying, and it died 10-15 days later.
Efficient grass-grass covers absorb conductive grass weed herbicides. It can be used in broad-leaved crop fields, that is, soybeans, cotton, beets, broadleaf vegetable fields. Annually, perennial grass acres with 35-50 ml, weeds difficult to remove such as reeds, sharp grass, Imperata and other mu agents 120-180 ml.
A lot of Taiwan products in spring, after the elimination of buds within the absorption of conductive herbicides, more than 150 species of crops more than 40 weed control effect is good, can kill perennial root weeds. Ordinary grass 150-200 ml, difficult to remove weeds 400-600 ml.
Gram-free US products, for the elimination of herbicides in contact with stems and leaves, can be quickly absorbed by plant green tissue. Illumination is an important condition for exerting efficacy, and spraying in sunny weather increases efficacy. The amount of mu is 100-300 ml, and the plants usually die in 2-3 hours.
Glyphosate-inhaled herbicides, kill a wide range of grass, has been used for many years, the effect is good, acres of use; general weeds 750-1000 ml, weeds 1500-2000 ml, deep-rooted weeding, shrubs 2000-2500 Ml. In particular, it was pointed out that the dispensing must add 0.2% detergent powder. If the weather is hot and dry, the use of fractionation is better than that of single use if the dose is not increased. That is, for the first time, use the full amount of 40% and spray it once every 3-5 days. There are two kinds of market sales, namely, 10% glyphosate and 40% agricultural water agent.
Trifluralin selective pre-emergence herbicide. It is mainly used in peach, apricot, grape, and walnut gardens. Good effects in some vegetable fields, annual weeds and certain broad-leaved weeds, such as gray vegetables, purslane, etc., which reduce annual grasses and weeds and seeds, and imperata, reed, wild, solanum, etc. Deep root grass is invalid. 100-200 ml of mu, more clay, more weeds, higher soil fertility, higher limit, and vice versa, immediately mixed with soil after spraying, depth 3-5 cm, low infertility, soil residual effect 3 - 6 months.
Relevant considerations:
1. Use clear water to dispense medicine. First add 10 pounds of water to the barrel, and pour the pre-formulated liquid into the barrel. Then add enough water to calculate the amount of mu according to the type, size and size of the grass.
2, choose no wind, fine weather, spray best after 4 pm. Raining after application will affect the efficacy, and deep rooted weeds generally die after 15 days.
3, in the long-term weeds, plant height 50-60 cm is best, the sprayer requires a spray hole is less than 1 mm, atomization should be fine, back spray, spray evenly, no leakage spray is not heavy spray.
4, for the fruit farm soil treatment agent requires more soil moisture, drought should increase the amount of water, mu liquid medicine about 120 kg, trifluralin must be mixed soil 3-5 cm deep.
5, each use sprayer to clean 3-5 times, so as not to cause injury.
Sun-Shading Net is a series of colored shade nets with special optical properties which improve the utilization of solar radiation by agricultural crops. This technology promotes differential stimulation of desirable physiological responses, which determine the commercial value of each crop. This is an economical and environmentally friendly alternative to current labor-consuming methods (such as pruning and thinning) and intensive use of growth regulators and other chemicals. ChromatiNet enables growers to control vegetative growth characteristics, such as leaf size, branch length and plant height in plants, as well as the rate of maturation and flowering. This enables adaptation to market preferences, with clear economic advantages.
Greenhouse Sun-Shading System can reduce solar load, and cool down the inside temperature and create a comfortable environment for the plants.
