Rapeseed antifreeze technology

In addition to the impact of climate conditions, rapeseed frost injury is also closely related to the technical management level of rapeseed fertilization, irrigation and soil cultivation. To prevent rape from freezing, comprehensive antifreeze measures must be taken, focusing on the following technical measures: 1. Selection of resistance Cold and hardy varieties, cultivate rapeseed strong seedlings. 2. Top-dressing Miao Fei, re-apply phosphorus and potash fertilizer, do a good job to prevent seedlings strong seedlings. Before winter, in combination with cultivating loose soil, timely application of Miao may promote vegetative growth of rape, promote the differentiation of leaf buds and flower buds, develop rape root system, grow plants robustly, enhance plant resistance, and reduce the occurrence of freezing injury. Therefore, it is necessary to do a good job of Miaofei. Top-dressing work. Miaofei topdressing should grasp the amount of nitrogen fertilizer application, increase the amount of phosphorus and potassium fertilizer or organic fertilizer, and promote mechanical growth of the plant. If the amount of nitrogen fertilizer is too much, and the application of phosphorus and potassium fertilizer is too small, it will easily lead to plant growth, and the ability to resist coldness will be weakened. , It is prone to frost damage. 3. Fill up the wintering water and do a good job of cultivating the soil. Pre-winter irrigation can reduce the temperature difference between day and night, improve the microclimate in the field, ease cold attacks, and prevent cold damage to rape. Overwinter irrigation should be filled and penetrating, with no water in the field as the limit. After the irrigation, the exposed roots should be re-cultivated, and the height of the soil should generally be cultivated to the first leaf of the base in order to facilitate root growth and prevent root extraction. 4. Remove the early moss early flowers. From late December to next January, it is the lowest temperature in Linxiang District. Therefore, before the beginning of spring, the flowering of bolting occurs. The buds should be removed in time to reduce the freezing injury. After picking, a fast-acting nitrogen fertilizer must be topdressed so that the nutrients in the plant body can be compensated. Promote its resumption of growth, promote more branches of rape, increase rapeseed yield.

Black Garlic Powder is extracted from black garlic, it can be used in the production of black garlic cookies, capsule, baked goods, etc.
