Orchard nursery using herbicide measures
When herbicides are used in nurseries of fruit trees, the types, dosage forms, dosages, and methods of use of the herbicides should be determined according to seedling growth, weeds, and weather conditions. Otherwise, the ideal weeding effect is often not obtained, but rather the phytotoxicity is suffered. Herbicides can be applied in the following two ways:
First, the spray method: suitable for spray herbicide formulations are wettable powder, EC and water and so on. General requirements for spraying the diameter of the fog below 100 to 200 microns. The fog point is too large, the adhesion is poor, and it is easy to lose; the fog point is too thin, it is easily blown away by the wind, and the amount of adhesion is reduced.
The preparations required for dispensing include: water tanks, buckets, filter gauze, stirrers, and the like. In order to accurately formulate the amount of drug, it should be set the container, the amount of drug, the amount of water, so you can avoid mistakes. The amount of drug should be weighed in advance with a balance or a relatively accurate small scale according to the size of the container, and packaged well, each time with a package. Use a fixed bucket to draw on the quantitative water line, and take water every time. The wrapped medicinal gauze is wrapped and dissolved in a small amount of water. The residue in the gauze is then removed and diluted with the required amount of water to form a liquid. The quantitative drug can also be dissolved in a small amount of water, fully stirred into a paste, and then add a fixed amount of water to stir evenly, that is, liquid medicine. The amount of water should be 30 kg to 50 kg per acre. The medicine should be used now and should not be stored for a long time.
Second, toxic soil method. Toxic soil is a mixture of chemicals and fine soil. It is generally preferred that the fine soil is sieved through a No. 10 to No. 20 sieve. The soil should not be too dry, and it should not be too wet. It is better to loosen the soil and automatically disperse it. The amount of soil is subject to uniform application, generally 15 to 20 kilograms per mu. If it is a powder, you can mix the soil directly; if it is a cream, dilute it with water first, then use a sprayer to spray it on the fine soil and mix well. If the dosage of the medicine is small, mix it with a small amount of soil and the medicine first, then mix it with the whole amount of soil and spread evenly.
