Question: in recent days, new music, twilight, etc., have called to ask when the spraying of drugs to suppress white art buds has begun
Zhao young liangbing: white arts can reduce the formation of buds and the consumption of ineffective nutrients, one of the effective measures to achieve high productivity in white arts。
White art is one of the commonly used varieties of chinese medicine. Management is more extensive and yields are higher, especially in recent years, when improved varieties have emerged, which are much more productive than traditional varieties. It became one of the preferred varieties of medicinal cultivation。
White art is one of the multi-sequenced and multi-sequenced species of herbivate potion. If white art plants produce more buds and flower seed on branches, there is competition for water with the tubers, which seriously affects the growth and production of white art roots。
The increase in the area under improved white seeds in recent years and the fact that white techniques are grown with improved seeds are less likely to produce more seeds in that year can reduce bud formation, alter nutrient transport and reduce inefficient nutrient consumption。
The traditional control of buds is artificial harvesting, which is not only time-consuming, but also the removal of the wounds left behind, which is highly contagious, can also result in a relaxation of the roots, damage to the well-established photocooperative group structure of the plant and affect normal growth。
Many growers now use pharmacological agents to suppress white-coloured buds, which are mainly luminous, absorbed by plants and then transmitted to active areas, accumulated in the masts, inhibiting the cell division of the top sub-organism, undermining the upper edges, inhibiting the growth of the lumber, controlling the growth of the sides, inducing male infertility, bringing the photo-codile products down to the roots and troughs and prolonging the length of the troughs。
1. In the case of plots planted with white seeds, between late june and mid-july, when more than 80 per cent of the top leaves of white seedlings grow into soybeans, 30 kg of water per acre can be sprayed evenly with 250 g of sprouts, 30 per cent of the acre, with an interval of 7 to 10 days, which is appropriate for two to three consecutive times。
2. In the late may to mid-june period, when more than 80 per cent of the top leaves of white art grow into soybean grains, 30 kg of water can be sprayed evenly at 30 per cent of acre, with an interval of 7 to 10 days and 2 to 3 consecutive times, and may continue to sow on a case-by-case basis。
