With the process of land intensification and the development of moderately large-scale operation, vegetable grafting and seedling cultivation has also been well developed, which can not only solve the problem of soil continuous cropping obstacles during the planting process of melon and fruit vegetables. Many growers suffer from the difficulty of operating without grafting techniques. Today, Hui Nongwang Xiaobian tells you how to grow eggplant grafting techniques and cultivation methods. Advantages of planting eggplant grafting Because the eggplant's Verticillium wilt, Fusarium wilt, bacterial wilt and root-knot nematode disease are soil-borne diseases, the bacteria survive in the soil for 3~7 years, and these diseases can only infect the cultivar's Solanaceae plants. It is almost harmless to wild Solanaceae plants. Therefore, the use of wild eggplant (such as Torumbaum) as a rootstock graft can effectively overcome the continuous cropping obstacles, and the grafted seedlings have strong growth and high yield, and have no adverse effects on fruit quality. 1, strong resistance to disease Torubum is used as a rootstock to achieve high resistance or immunity to soil-borne diseases such as Verticillium wilt, Fusarium wilt, bacterial wilt, and root knot nematode. 2, high output The rootstock has developed root system. The grafted plants have strong growth potential, long fruiting time, and the yield per plant is 2~3 times that of non-grafted seedlings. The appearance quality of the fruit is much better than that of non-grafted seedlings. 3, easy to grow The disease resistance, heat resistance, cold resistance and mites resistance of rootstocks are far superior to non-grafted seedlings, and seedlings are easy to grow after grafting. 4, good quality The grafted eggplant has good appearance quality, and because of the strong disease resistance of the plant, the spraying is less during the planting period, the food safety is more secure, and it is more favored by customers. Planting eggplant grafting technology 1. Planting density The number of 667 m2 plants is about half of the seedlings, and 600 plants/667 m2 for large-scale planting; the spacing between sporadic plants is not less than 80 cm. 2, planting depth The planting should not be too deep, the grafting site should be higher than the soil by more than 5 cm. After the planting, the regenerated roots on the scion should be inspected and erased; if the grafting site is buried in the soil, the soil-borne disease will be transmitted from the scion regenerative root to the plant, thus losing The role of rootstocks in disease resistance. 3, wipe out the sprout Germination on the rootstock should always be erased, otherwise it will affect the growth of the scion. Other matters refer to non-grafted eggplant seedling cultivation techniques. Eggplant grafting cultivation method Since the number of planted grafts of eggplant is only about half of that of seedlings, if the seedling age is too small when planting in spring, the early yield will not come up; if planted according to the density of non-grafted seedlings, not only the seedling cost is high, but also the crowd will affect the follow-up Growing. It is recommended to choose the following cultivation methods. 1, nutrition cup fake In Lidong (November 7th) to the winter solstice (December 22nd), use 12cm × 12cm nutrition cups to plant grafted seedlings, pay attention to the bottom of the nutrition cup to prevent the rootstock from sticking into the soil; if there is after the winter solstice The frost covers the small arch shed for heat preservation, and is fixed until the beginning of the spring (around February 3) without frost. In this way, the investment cost is small, the risk is low, the fruit is frozen early after planting, the output is early, and the later is not long. It is generally recommended that farmers use this method to cultivate. 2, open field planting It is directly exposed to the ground during the winter to winter solstice. When the winter solstice reaches the spring, there is a small arch shed covering the heat preservation. This cultivation method has high income in the early stage, but the investment is large and the risk is high. This method can also be carefully chosen by experienced vegetable growers or frosty microclimate areas (such as urban areas and near heat source plants). The above is the cultivation of eggplant grafting technology and eggplant grafting cultivation method compiled by Huinong. I hope to help you.
