Wheat pre-winter weeding saves labor and labor

At present, the weeds in the wheat fields of most wheat fields in the north have been unearthed gradually, and the main grasses of malignant grasses are bromegrass. Broad-leaved weeds are dominated by sow wormwood, leeks, and wheat grasses.

In recent years, although more and more varieties of herbicides have become more expensive, the control effects of broad-leaved weeds such as leeks, sowing wormwood, and swine fever have become worse and worse. With the implementation of the operation of the machine-cutting zone of wheat, the grassy weeds that come with it are also widespread and harmful. Many people do not pay attention to the growth of weeds in the fall, and often miss the appropriate timing of prevention and control after the discovery in the spring. They can only grazing on the growth of dense wheat weeds and cause loss of yield. In fact, in the autumn, with the emergence and growth of wheat, various weeds will be gradually unearthed. At this time, the weeds will grow young and have a weak resistance to insects. Using low-dose, low-water quantities of common herbicides will save time and labor. The effectiveness of the control is the best time to use drugs.

As most of the weeds in wheat fields are unearthed before winter, the grasses are young in this period, and there is little shading in the field, and the use efficiency of pesticides is high. The control effect is ideal, and it can also effectively prevent phytotoxicity to surrounding crops. Therefore, vigorously advocating wheatgrass autumn governance is of great significance for ensuring high yield and stable wheat production.

Agricultural experts suggest that grass weeds usually occur in the 3-5 leaf stage of wheat and at the 2-4 leaf stage of weeds (about from the end of October to the beginning of November), and 70% of the lands with the main production of bromegras can be selected.彪 Tiger or preferential spray control; plots dominated by the occurrence of Aegilops tauschii were treated with 3% Smarma or 3.6% konshima spray. For the broad-leaved weeds that are mainly unearthed before the winter or have a large amount of unearthed soil before the winter, 10% of tribenuron-methyl, 2,4-D isooctyl ester can be used as the broadleaf weeds. , Kuai Ling Ling, make it Long, Pentium, Mai Xi and other agents spray control.

Experts remind that the majority of growers should adopt the double dilution method when preparing pharmaceuticals in order to improve the efficacy, and the water consumption per mu is not less than 30 kg. In addition, due to the use of weeds in autumnal dynasty, it is easy to encounter adverse conditions such as rapid cooling, high winds, etc., and the time of medication should be used to ensure that all types of weeds in wheat fields are basically seedlings, and the choice of sunny minimum air temperature is not less than 4°C.

Active Pharmaceutical Ingredients

Active Pharmaceutical Ingredients(API) refer to the raw materials used in the production of various preparations. They are the effective ingredients in the preparations. They are various powders, crystals, extracts, etc., prepared by chemical synthesis, plant extraction or biotechnology, but Substances that the patient cannot take directly. API is intended to be used in any substance or mixture of substances in the manufacture of pharmaceuticals, and when used in pharmaceuticals, it becomes an active ingredient of the pharmaceuticals. Such substances have pharmacological activity or other direct effects in the diagnosis, treatment, symptom relief, treatment or prevention of diseases, or can affect the function or structure of the body. According to its source, active pharmaceutical ingredients are divided into two categories: synthetic chemical active Pharmaceutical ingredients and natural chemical active Pharmaceutical ingredients.
