Four Methods for Improving the Survival Rate of Courgette Grafting
Zucchini plants are susceptible to wilt disease in successive years. Grafting can prevent the occurrence of wilt disease in zucchini, and can greatly increase the yield of zucchini. However, if the grafting technology is not well-handed, the survival rate of grafting will be low, which will affect the yield and benefit. The measures for the survival rate of grafted cucurbits are briefly described as follows: 1. Cultivate strong seedlings: Robust seedlings are the basis for increasing the survival rate. Seedlings require thick stems, leafy greens, and flat cotyledons that are uncovered without caps. In particular, stem diameter has a great influence on the survival rate. It is necessary to make the rootstock of the rootstock and the scion coarsely consistent. 2. Reasonable humidity control: In the first 3 days after grafting, the humidity should be controlled between 96% and 98%. It is required to be irrigated after grafting, and sealed tightly around it to prevent the cold wind from entering, so as not to affect the survival rate of grafting. After 3 days, the wounds basically healed, and the air humidity can be properly reduced. Generally, the air is ventilated twice a day. Later, the ventilation time is gradually extended, and the shade net and arch shed are promptly removed according to the situation so that the seedlings gradually adapt to the external environment. 3, reasonable control of temperature: temperature management is to improve the survival rate of grafting is the key, when grafting to do a good job of insulation and cold work, when the seedlings are suitable for grafting, to be selected in the sunny and timely grafting, grafting to use high shading rate shade nets for shading To maintain a certain temperature in the grafting shed, to prevent high temperature burns and wounds caused by excessively low temperatures, and to affect the survival rate of grafting. 4, seedling management process: should prevent excessive soil moisture and damping-off occurred in the grafted seedlings in the water to be poured by adding carbendazim or thiophanate-methyl and other fungicides, pouring sole water, generally in the entire The healing period is no longer watered, so as to avoid excessive watering and affect the healing of the wound. If you are too dry when growing, you can pour small water properly. Short range distance sensors from JRT combine highly precise measurement results with quick and reliable response. Short distance sensor module use single-transmit and single-receive measurement technology and can be used to measure a distance or monitor the slow moving objects. For the laser pointer distance measure, also called optical range sensor, can measure legth, width, depth. Laser rangefinder transducer with rxtx has been widely used to industries.
