Rapeseed segmentation and fruiting can lead to an increase in the number of ineffective fruit of individual plants and a decline in yield, generally requiring a reduction of production by 10% to 15%. The symptom of rapeseed segmentation and solidification is that some flower buds of the effective inflorescence segment have not been opened and are yellowing off. Or can normally flower, but can not normally develop strong pods that wither off: Some flowers even if they can develop into pods. However, they are only about 1 to 5 grains of radish pods, which causes the inflorescences to appear segmented and solid. The main reason for these problems is the long duration of low temperature: the species has poor cold resistance. Or due to lack of boron in the soil. In addition, partial application of nitrogen fertilizer, continued drought, pest damage, will also have a certain impact. How to prevent and overcome the rape knot segmentation image? Based on the years of practical experience of farmers in Wuning County, Jiangxi Province, the following measures can be taken: 1. Select high-yield and high-quality varieties such as “Zheyouza No.1†and “Huaza No.3†for varieties with large yield potential and strong cold resistance. 2. Timely early sowing, nurturing strong seedlings, ensure timely transplanting and early planting of transplanting quality, so that rape can form a larger vegetative body before winter. It is conducive to safe wintering of rapeseed. Therefore, the general area should be sown in mid-late September and transplanted in mid-to-late October. Age 25 to 30 days. 6 to 7 green leaves, 20 to 23.3 cm in height, and 0.6 to 0.7 cm thick root shoots were bred. When transplanting, it is necessary to use phosphorus fertilizer to root, fire soil manure, pouring a good set of root water. To make strong seedlings early. Transplanting density: 6000-7000 plants per 667 square feet (1 mu) planted in cotton. Rice fields are planted between 8,000 and 10,000 plants per 667 square meters. 3. The application of boron fertilizer rape is very sensitive to the boron reaction, especially in the boron-deficient soil application of boron fertilizer. It is an effective measure to prevent rape from being unrealistic. Specific use of methods: borax 250 to 500 grams per 667 square meters. Mix well with dry fine soil. Directly apply basal or seed fertilizer before sowing. When topdressing, the borax is first dissolved in warm water, and then evenly into manure water or urea water, showering in the early stage of seedlings. Foliar spraying, with 0.2% ~ 0.3% borax solution in the seedling stage, spraying season. At the same time, in the fertilization technology, we must also prevent partial application of nitrogen fertilizer, pay attention to the application of phosphorus and potassium fertilizer, which also has a great role in preventing rapeseed segmentation and solidification, increase seed-setting rate, and increase yield. 4. Prevention and control of pests Sclerotinia sclerotiorum, downy mildew and white rust hazards, but also cause the loss of fruit and fruit or the phenomenon of Yinjiao particles, must pay close attention to prevention and treatment. (1) Sclerotinia: In addition to doing a good job of agricultural control, it is effective to use 30% wettable sclerotinia powder or 50% wettable carbendazim powder 500 to 1000 times spray from early flowering to full bloom. (2) Downy mildew. White rust: The population collectively referred to the leading disease. During the convulsive period, the old leaves and diseased leaves of the base were stripped off and when they saw the faucet, they were immediately cut off. Concentrated burning, and spray 50% wet thiophanate powder 800 ~ 1000 times liquid. Apply every 5 to 7 days, continuous control 2 to 3 times. Good results can be achieved.
