Information
The planting of zucchini is susceptible to blight in successive years, and the grafting can prevent the occurrence of zucchini wilt, and can greatly increase the yield of zucchini. However, if the grafting technology is not well mastered, the grafting survival rate will be low, which will affect the yield and benefit. The measures to improve the grafting survival rate of zucchini are as follows: Cultivate strong seedlings Strong seedlings are the basis for improving the survival rate. The seedlings require thick stems, green leaves and cotyledons to be flat and unearthed without caps. In particular, the stem diameter has a great influence on the survival rate, and the stems of the rootstock and the scion should be as uniform as possible.
Reasonable humidity control
The humidity should be controlled between 96% and 98% for the first 3 days after the grafting of the zucchini. It is required to pour water after grafting, and the surrounding seal is tight to prevent cold wind from entering, so as not to affect the graft survival rate. After 3 days, the wound is basically healed, and the air humidity can be appropriately reduced. Generally, the air is ventilated twice a day. Afterwards, the ventilation time is gradually extended, and the sunshade net and the arch shed are removed in time according to the situation, so that the seedlings gradually adapt to the external environment.
Reasonable temperature control
Temperature management is the key to improve the survival rate of grafting. When grafting, it is necessary to do warm and cold protection work. When the seedlings are suitable for grafting, they should be grafted in sunny days. When grafting, they should use high shading net shade to shield the shed. A certain temperature prevents the high temperature burning and wound loss due to excessive or too low temperature, which affects the graft survival rate.
The management of seedlings should prevent the temperature of the soil from being too high and cause catastrophic disease. When grafting the seedlings, add bactericide such as carbendazim or methyl thiophanate in the water to be poured, and pour the bottom water, generally during the whole healing period. Watering again to avoid watering and affecting the healing of the wound. If it is too dry during growth, a small amount of water can be properly poured.
