Not because the weak cucumbers on the seedlings keep growing
Recently, when the reporter interviewed Dongjiayingzi Village in Luocheng Street, Shouguang City, he discovered that Zhang's planting of a good cucumber seedling still did not break its roots. “It was planted for six or seven days. The cucumber seedlings grafted this year are very weak. In order not to delay colonization, I planted it without cutting off the roots. This way, the seedlings will grow faster. Seeing the seedling grows well now, I wouldn’t hurry to cut it.†Master Zhang said with a smile. Listening to Master Zhang's explanation and looking at the current growth of cucumber, there seems to be no problem. However, in the long run, the reporter believes that Master Zhang's abuse of this practice is a lot, mainly in the following points: First of all, the resistance to disease and stress of cucumber plants at the seedling stage is relatively weak. In addition, the root system of the seedling will inevitably be injured when transplanted, and it is very easy to be infected by the bacteria. It is best to cut off the roots before planting and keep the roots of pumpkin rootstocks with strong disease resistance to avoid root diseases. Thirdly, when the cucumber is grown in the early stage, there are few leaves and the nutrition is little. If the roots are not timely cut before transplanting, the photosynthate produced by the leaves will be supplied to the roots of both groups and the nutrient supply will be insufficient. Both groups cannot develop a developed root system, especially The poor development of the pumpkin roots is not only not conducive to the absorption of nutrients, but also reduces the resistance to disease and stress of the plants. In addition, vegetable farmers use white seed pumpkin as the rootstock grafting. It is very important to use the characteristics of the white-seeded squash to the wax powder, and the melon strips have better brightness. If the cucumber is not timely cut off the roots, it will inevitably reduce the ability of the plants to wax powder, so that the melon strip brightness is reduced, the commercial character is deteriorated, and the whiteseed pumpkin is lost as a major advantage. For cucumber seedlings, continuous rooting or root cutting and then rooting or cutting roots, etc., will affect the growth of cucumber, and even lose the significance of grafting. The reporter suggested that Zhang Zhang must seize the opportunity and take root in a timely manner. After the planting, the root cut should be selected at about 4 o'clock in the afternoon to facilitate the easing of seedlings after the break. When the roots are cut off, the blade can be cut at 1 cm below the cucumber grafting interface and it must be completely removed. After the roots were cut off, 75% chlorothalonil 600 times and 3% endotoxin were sprayed 600 times to prevent diseases. 1) ESCO MEDICAL has founded in 2002 and located in Suzhou China.
