Eggplant head regeneration and pruning method without putting up frame

Abstract

The invention discloses an eggplant head regeneration and pruning method without putting up a frame. The method includes: using a 2-3 stem pruning method before the fourth fruit of eggplants, that is to say, reserving one lateral bud below the first fruit of the eggplants to form 2-stem branches, reserving one lateral bud below each of two pair eggplants to form 4-stem branches, reserving 2-3 main stems and removing all the rest lateral branches; cutting the branches during harvesting of the fourth fruit of the eggplants, selecting one robust lateral bud with a flower bud among leaf axils below fruit to serve as a fruiting branch, reserving 3-5 lateral branches of lateral buds germinated on the fruiting branch at any time for fruiting, cutting off the branches during harvesting, selecting the lateral bud with a flower bud among leaf axils below fruit for continuous growth, and repeating the process. The small greenhouse double-cover open-field eggplant one-year-one-crop cultivation adopts the continuous head regeneration and pruning method without putting up the frame, plant growth vigor is high, plant type is compact, lodging resistance is achieved, later fruit is regular, good in coloring and good in commodity, high continuous fruit bearing capability is achieved, high yield is achieved, manpower and labor are saved, cost is saved, and efficiency is increased.

Description

technical field [0001] The invention relates to a method for pruning eggplants by changing heads without setting up a frame, which is used for high-yield and high-efficiency cultivation of eggplants with double covering in small sheds and once a year in the open field. Background technique [0002] Eggplant is one of the important solanaceous vegetables. In early spring, double-covered small sheds and open-field cultivation of eggplant have a large planting area. Due to relatively simple management techniques and high input-output ratio, it is one of the main forms of eggplant cultivation. In principle, double-covered small sheds and open field cultivation of eggplant need to be erected, and seedlings are drawn from the end of July to the end of October. The planting density per mu is 1800-2000 plants. There are mainly two methods of pruning in production. One is to remove all the side branches below the eggplant, and then pruning according to the branching habits of eggplan...

There are mainly two methods of pruning in production. One is to remove all the side branches below the eggplant, and then pruning according to the branching habits of eggplant, that is, to keep a side bud below the first flower of the main stem of eggplant to form the first "ya" with the main stem. Type 2 rod branches, with 2-3 leaves on each branch and then 1 flower, and a side bud under the flower is retained, forming the second "ya" type on the 2 branches, a total of 4 rod branches, 2-3 leaves are attached to the branches, and then 1 flower is attached to each branch, and a side bud under the flower is retained, and the third "ya"-shaped 8-pole branch is formed on the 4 branches, correspondingly forming phyllum, For eggplant, Simendou, Bamianfeng and other fruits (theoretically, but not so many fruits in practice), this method is often used in the cultivation of eggplant in the open field. This pruning method is extensively managed, with too many side branches, and the stems and leaves will be closed in the later stage. , the plants are rickety, the fruit is too small, and the coloring is not good, the commodity value is poor, and the occurrence of diseases and insect pests is serious.

The second is 4-pole pruning, that is, all the side branches below the eggplant are removed, and a side bud is reserved below the first flower of the main stem of eggplant, forming the first "ya" type 2-pole branch with the main stem, and 2- After the 3 leaves, 1 flower is born, and a side bud under the flower is kept, and a second "ya"-shaped branch is formed on the 2 branches, and a total of 4 branches are kept, and 4 fruiting branches are kept. This method is double-covered in a small shed. It is more common in middle-aged plants, and it is necessary to set up a frame or pull wires to prevent lodging. After this pruning method is harvested, as the plant grows taller, the upper stem becomes thinner, and it is easy to break after fruiting. At the same time, the fruit gradually becomes smaller. The color is gray, the commerciality is poor, and the output is low in the later stage
