How to manage rapeseed cultivation? Key technical points explained in detail
How to prevent and control rice "sitting stump" disease? Please help. Rice "sitting stump" disease, namely rice red blight, is a common physiological disease in rice production. It generally begins to develop about 15 days after transplanting. If a cold wave occurs after transplanting, in cold-waterlogged fields, muddy fields, deep-water fields, fields where undecomposed organic fertilizer has been applied, fields with one-sided application of single-element chemical fertilizers, or fields lacking potassium...
How should rapeseed be managed during cultivation? Please advise.Rapeseed is one of the main oilseed crops in China. Cultivation methods fall into two types: seedling raising and transplanting, and no-till direct seeding. At present, most planting regions mainly adopt the seedling raising and transplanting method. The main measures are as follows:
1. Sufficient fertilizer and adequate soil moisture, transplant strong seedlings, and maintain rational close planting. Whether raising seedlings in a seedbed or in the field, ensure sufficient fertilizer and adequate soil moisture, and that the soil is free of pests and diseases. Sow according to the farming season, and spray New High-Fat Film to preserve soil moisture and fertilizer effectiveness, prevent pest and disease attack, and promote strong seedlings. When transplanting, select upright seedlings with well-developed root systems and uniform, healthy plant bodies, and plant them at a rational density. After transplanting, spray New High-Fat Film, which can protect the leaf surface, preserve soil moisture, prevent pests and diseases, effectively promote the healing of root wounds and rapid growth, and effectively prevent cold damage and ensure overwintering.
2. Weed and loosen the soil, preserve both fertilizer and soil moisture, and strengthen the plant and thicken the stems. After turning green in spring, carry out intertillage and weeding to prevent soil compaction, preserve soil moisture, and eliminate competition for water and nutrients, and spray New High-Fat Film to enhance the effects of the above functions. During the bud and bolting stage, spray Zhuangsui Ling to strengthen the physiological functions of the crop, so as to enhance the smooth transport of nutrients in the plant, strengthen seedlings and stems, promote the absorption of nitrogen, phosphorus, and potassium and the supplementation of trace elements, facilitate bud and bolting formation, improve the pollination and fertilization quality of rapeseed, increase the thousand-grain weight, and promote the rapid and robust growth of pods, laying the foundation for a bumper harvest.
3. Prevent and control pests and diseases, combine physical and chemical methods, and focus on effectiveness. Rapeseed faces many troubles throughout its life, with complex pests and diseases. At the seedling stage, mainly strengthen control of pests such as cabbage caterpillars, aphids, cutworms, and mole crickets, as well as downy mildew. At the flowering stage, mainly control sclerotinia and prevent excessive vegetative growth. At the green pod stage, mainly strengthen control of aphids and white rust. For the control of these pests and diseases, in addition to using highly targeted pesticides, New High-Fat Film should also be added, which doubles the control effect.
