Embodiment 1
[0015] The cultivation method is realized in the following steps:
[0016] Use tomato variety "Jinguan 5" as rootstock (or use Jinguan 8, Baoguan 1, Jinpeng 1, Liaoyuan Duoli, Jiayuandafen, L404, Mawa as rootstock); "Eggplant" as scion (or use Xi'an green eggplant, purple round eggplant, Liyuan purple eggplant, black and bright, Liao eggplant No. 5, purse eggplant, light bulb eggplant, Meifeng long eggplant, Britta, Nile, and Andrea for scion).
[0017] Adopt the existing cleaving grafting method. After the grafted seedlings survived, they were planted in the solar greenhouse that had been continuously cropped for 3 years. The seedlings were planted with a row spacing of 70 cm and a plant spacing of 50 cm to make 18 cm high borders or high ridges. The position of the grafting knife edge was 5 cm higher than the ridge surface. Self-rooted seedlings without grafting were used as controls. 30 days after planting, the "special double-pole pruning method" was used for plant adju...
Embodiment 2
[0022] The cultivation method is realized in the following steps:
[0023] The wild eggplant "Huangguo eggplant" was used as the rootstock (or the rootstocks were Huangtian eggplant, Echinopsis eggplant, Echinopsis eggplant, Wild sea eggplant, Linglong eggplant and milk eggplant), and the eggplant variety "Liaoqie No. 5" was used as the scion ( Or use Xi’an green eggplant, purple round eggplant, Liyuan purple eggplant, black and bright eggplant, purse eggplant, light bulb eggplant, Meifeng long eggplant, Britta, Nile, and Andrea as scions). Grafting using the existing split grafting method. After the grafted seedlings survived, they were planted in the solar greenhouse that had been continuously cropped for 3 years. The seedlings were planted with a row spacing of 70 cm and a plant spacing of 50 cm to make 18 cm high borders or high ridges. The position of the grafting knife edge was 5 cm higher than the ridge surface. Self-rooted seedlings without grafting were used as contr...

Abstract
The invention relates to a cultivation method for overcoming continuous cropping obstacle of eggplants, which is characterized by taking tomatoes or wilds tomatoes as parental stocks and taking coins as an eggplant variety; respectively culturing parental stock seedlings and coin seedlings, grafting and seedling by a cleft graft method to form eggplant graftings combining the parental stocks and the coins, fixedly planting the seedlings after the seedlings survive; making high plots or high ridges of 18cm, and fixedly planting the grafted seedlings in accordance with the row spacing of 70cm and the planting distance of 50cm, wherein the position of a grafting cutter point is 5cm higher than that of the ridge surface or the plot surface; carrying out plant adjustment by a double-rod pruning method after fixed planting to promote the germination of lateral branches, repeatedly carrying out topping treatment to generate multiple lateral branches, thus forming multiple fruits; and culturing until the eggplants mature. In the invention, the grafting and the root changing belong to the biological agronomic measures, the operation is simple, the application is convenient, no pollution is generated to environment and agricultural products during the process of production, and the high quality of the agricultural products can be maintained. The seed source of parental stocks is easily to obtain, the production cost is low, the effect on overcoming continuous cropping obstacle is obvious, and the purposes of continuously planting eggplants in the same block and plastic tent and realizing stable production can be achieved.
Description
technical field [0001] The invention relates to the technical field of modern vegetable cultivation. Specifically, the present invention relates to a cultivation method for overcoming obstacles in continuous cropping of eggplant. Background technique [0002] Eggplant is an important vegetable in our country, and it is also a vegetable that should not be cropped continuously. With the rapid development of protected vegetable production in my country, the planting area of eggplant is constantly expanding, so the phenomenon of continuous cropping is also very common, and the problem of yield reduction due to continuous cropping obstacles has become increasingly prominent, which has become an important issue affecting the sustainable development of eggplant production in my country. The main hazards after continuous cropping are: the aggravation of soil-borne diseases, the accumulation of autotoxic substances, the change of microbial flora, and the decline of soil performanc...
