First, the emergence of the valley is not neat, the uneven growth of seedlings, the formation of the size of seedlings, large seedlings pressure seedlings, strong seedlings pressure weak seedlings, the weak seedling nutrient supply is insufficient, not back on the package, resulting in slide bar.
Second, after the jointing of the valley, the supply of water and fertilizers is not enough, and the seedlings are yellow, causing the development of the ear to be frustrated. No backpacks or knapsack will cause knots.
Third, Baogu has been planted densely, and the slider bar will also grow. Because the seedling trees are too dense and shade each other, the conditions for ventilation and light transmission are poor, photosynthesis is reduced, the formation of organic substances is reduced, and no knots can be formed.
In order to prevent and control Baogu sliders, we must pay attention to several issues in cultivation and management:
First, adhere to a reasonable and close planting. According to the difference (characteristics) of the characteristics, area, soil, climate, soil, fertilizer, water, cultivation and management level of Baogu varieties, the planting density is not the same. Therefore, it should be adapted to local conditions and be closely planted. Planting 3000-500 strains of high-cultivated varieties per acre, planting medium-sized varieties, planting 3500-4000 plants per acre, and planting compact varieties, 4000 plants to 5000 plants per acre. At the same time, it is necessary to improve the sowing methods, such as the use of wide and narrow row drills or intercropping. In this way, it will not only improve the land utilization rate, but also improve the conditions for ventilation and light transmission between the Baogu lines and reduce the number of sliders. At the same time, it is convenient for the management of cultivating the farmland. After ramming soil, the culverts will be narrow, and the gorges will be wide, which will also facilitate flood drainage and drainage.
Second, we should sow good seedlings and strengthen seedling management. The seedlings should be sown well to ensure that the seedlings are fully grown, seedling management is strengthened, fertilizers are added to weak seedlings, and seedlings are caught as soon as possible.
Third, Baogu jointing after booting, it is necessary to reapply a looting fertilizer. Because Baogu enters the jointing and booting stage, it needs more water and fertilizer, especially 10 days to 15 days before the day of flowering. It is during the period of ear differentiation that there is sufficient supply of water and fertilizer to prolong the differentiation time of the ear, and the full growth of the package is achieved. The purpose of high and stable production.
Why does Baogu slide?
Farmer friends, you may often see that some Baogu only grow seedling trees, will not backpack, grow into a slider (empty). So why does Baogu slide it? The baggage slider generally has the following reasons:
