In order to strengthen the technical guidance service for seedseed and vegetable field management to capture the harvest, the technical guidance for the management of fields in the later stages of seed and seeds in guangxi is being issued to you。

Our region is now entering the reed season in turn, and later in january will enter the flowering season in turn, which is the critical period in which the vegetable buds divide and produce. The next step is to pay close attention to the seed oil-receiving field management services, focusing on resistance, flower promotion, insect prevention, winterization and conservation, in an effort to capture the 2025 harvest。
I. Strengthening water fertilizer management
Reach and flowering periods are peaks of water for oilseeds, water-deficit fields should be made more widely available, water canals, reservoirs, etc., should be used to enhance water distribution. Drift irrigation should be “run-down” in such a way that it can be quickly drained, free from water accumulation and free from flooding. Areas with insufficient water sources should be replaced by mechanical water pumping, running water, hand-picked water irrigation, etc. In the case of oilseeds, such as red-haired leaves and red-haired fertilization, timely counter-retroactive measures should be taken. Areas without irrigation conditions can be sprayed in the form of leaf spray, mixed with high nitrogen amino acid water soluble + potassium hydroxyphosphate + platinum/bili+ water soluble fat. Increased water use is appropriate for spraying, with 3-5 litres per acre spray by drones and more than 30 litres per acre by mobile aerosol operation。
The late broadcasting of oilseeds should be followed up in early january with the application of fertilizers. Cultivation of 5-10 kg of urea, or application of leaf pasta, water soluble fertilizers etc. Accelerates nutrient accumulation. Low-fat oil and vegetable fields should be followed up with fertilizers during the cabbage season in order to promote the sprouting of plants. Fertilizer usage: 5 kg/acre of nitrogen (n), 3 kg/acre of potassium fertilizer (k2o), 0. 2 kg/acre of boron fertilizer (bone sand), with an appropriate increase of 20%-30% in urea, potassium chloride, boron fertilizer, evenly mixed with urin, potassium chloride and permafrost, as well as the application of the corresponding nutrients of potassium permanganate. The paddy fields should be filled with water and fat. Short-term rainfall is often associated with cold air activity, with close attention being paid to weather changes and to catching up with good times。
Ii. Strengthening pest control
The persistence of dry water shortages will result in reduced resistance to oilseeds and a high incidence of pests and diseases. There is a need to keep a close eye on the occurrence of oilseeds and pests, and to organize timely operations to control them and ensure their health。
In the later stages of the oil course, special emphasis is placed on pests such as larvae, aphids and yellow cape, as well as diseases such as bacterial nuclei and frost. Vegetable chlamydia can be treated with imams, efficient cyanide, cyanide, cymethrin, avimoxin, etc.; aphids may be treated with the green fungus of gold turtles, cqma421 biological formulations, or cymethrin, aphids, etc.; piping may be treated with acrystasy, acne, acne, ethyldomide, ethyldomicides, etc.; bacterium nuclei can be treated with accetosis, etc。
Implementation of the “one to four protections”
In the early years of oil and vegetable production (which starts with 25 per cent of the field's plants), a combination of fungicides, insecticides, potassium phosphate, water soluble botilizers, plant growth regulators, etc., flower-proofing, prevention of premature decay, pests and pests, heat protection, increase in the number of horns and grains, and promote the production of oil and vegetables。
Iv. Watch out for cold and cold
According to meteorological projections, some parts of the north of guiana may have frost or cold rain, oilseeds in the buds to bloom are vulnerable to low temperatures and timely measures are needed to combat the cold. Low-temperature rain and snow freezing weather is preceded by timely clean-up of the “three ditches” to ensure smooth drainage of the fields' ravine, girdles, girdles and girdles, without water in the fields, and to prevent the occurrence of accidents; excessive oils, which can be increased by phosphorus fertilizers or multi-effic-controlled leaves, which can be used in time to remove the main bouquets, promote side branch growth and mitigate the effects of cooling on production; and, conditionally, plant growth regulaters, anti-immunoserants, etc., on 2-3 days before the onset of low temperatures, which can increase the temperature on the ground and increase the capacity of the vegetable to withstand cold; and so on in the fields, which can be shown to increase the temperature of the ground and increase the amount of calves。
V. Post-disaster prevention and mitigation benefits
In march, our region entered the ointmental period, during which rainy weather should be filled with water in time to prevent contamination, while focusing on diseases such as nuclei, frost and powder. Drought weather focuses on pests such as aphids and moths。
The harvest period coincides with the early planting of rice, and in order to increase the efficiency of early rice harvesting, it is advisable to scale up mechanical harvesting. The preferred oilseed combine harvester may also be modified by adding a grain combiner to a forced shearing device (side-stretching knife), a long long cutting table (with an increase of about 30 cm), adjusting the speed of the detaching roller, dent-screeching gaps, wind-screeching, replacing the scavenger, adjusting the opening of the scavenger. At the time of the harvest, the cut would be 20-30 cm. Usually, the harvest begins about 30 days after the end of the vegetable season, when more than 80 per cent of the herd's corneas are in the white and the upper is not completely yellow. In order to promote consistent maturity and reduce harvest losses, e. G., ethylene, ethylene fluoride, nisulfon, dichlorfluorine, etc. May be sprayed。
