Key Techniques for Regeneration Cultivation of Eggplant Eggplants in Protected Field

Eggplant Hibiscus regrowth cultivation technology is a technology that uses the new branches of the middle and lower parts of the trunk before the end of or after the end of the production of the oyster eggplant to re-smear and bloom. 1. Suitable for regeneration cultivation of regenerated eggplant varieties, medium and late-maturing varieties with strong growth potential, strong branching, cold resistance, disease resistance, and good commercial quality should be selected. Such as Ziyang long eggplant, Ji Nongchang eggplant number 1, and so on. 2. The eggplant is regenerated and cultivated in the form of eggplant. Regeneration of the eggplant varies according to the position of the regenerated shoot on the plant, and is divided into two forms, the central regeneration and the lower regeneration. 2.1 Central regeneration. In the middle of the plant, the regenerated shoots were selected, and the position of the regenerated shoots was relatively strong. The growth potential was strong, the hair trees were early, and the growth was fast. At the same time, the buds on the regeneration shoots had better quality and the results were earlier, and the fruit setting rate was higher. In addition, the upper part of the plant light conditions are better, is conducive to fruit growth, fruit quality is relatively good. If it is a short period of regenerative cultivation, this type of regeneration should be selected. 2.2 Lower regeneration. In the lower part of the plant, the regeneration ribs are selected, and the regeneration twigs are generally retained from the main stalks under the phylum. The lower regenerated shoots have a relatively large cultivation space, a long cultivation time, and easy production of high yields. If it is grown by reclaiming technology, the lower regeneration form should be selected. 3. Technical points for regenerating eggplant cultivation The core of rejuvenation cultivation technology management is to increase the supply of fertilizers and water through pruning and pruning, so as to promote the emergence of new strong shoots, generate new lateral branches, and regenerate vigorous plants. And again the result of the peak period. 3.1 Trimming time. The suitable regeneration time for high-yield cultivation of greenhouse eggplant year after year is from late August to mid-September, with 1 cut per year. After the end of spring production in general, no more fruit is left, no longer pruning, cultivation of plants, rejuvenation. 3.2 Pruning methods. When pruning, cut the upper branches 15 to 20 centimeters from the trunk. The cut branches and weeds were cleared out of the greenhouse and topped with water to promote new shoots, but care must be taken to keep 2 to 3 buds that have germinated under the cut. If there are no germinating buds in the lower part of the plant, pruning should be carried out twice. First pruning should be done at 10 cm above the eggplant, and after the buds are sent out, the second pruning should be performed. Otherwise, some plants will be unable to absorb and Feed nutrients and die. 3.3 cultivating loose soil and fertilizing soil. After the plants have been pruned, in order to speed up the emergence of new shoots and grow new lateral branches, timely cultivating loose soil and fertilizing the soil are required. First remove the old land touches of the previous year, use the hoe to loosen the sides and the middle of the cultivating ridges fully, and then bury the high-quality farmhouse fertilizer 3 cubic meters per mus, the urea 20--30 kg, potassium sulphate per acre in the middle ditch. 10--15 kg, then earth, cultivate 20 cm high cultivation ridges, and poured 1 large water. 3.4 Pruning. Under the above management conditions, axillary buds can form lateral branches 8-10 days after pruning. At this time, one layer of new mulch is timely covered on the ridge, and one or two or three strong lateral branches are selected for flowering results. When leaving one lateral branch, branching is still performed after double branching in the future. For each of the lateral branches of the plants with 2 to 3 lateral branches, one was the stem, and the remaining lateral branches were all erased. Regeneration branches generally grow obliquely upwards, and they should be fixed and fixed as soon as possible. In addition, because the regeneration branches of different plants occur differently in the morning and at night, the height of the plants is not the same, and the growth potential of the plants should be adjusted in time according to the growth of the plants to prevent the height difference between the plants from being too large and maintain the orderly growth of the field. 3.5 fertilize irrigation. About 1 month after the plant is trimmed, the eggplant can bloom. When 50% of the plants see the fruit, the fertilizer and water supply. Master 10-15 days, pour 1 water, every time the water chase 1 fertilizer, every time, apply 20--25 kg urea per mus, potassium dihydrogen phosphate 5 kg, pay attention to topdressing potassium sulphate fertilizer, but also foliar Spraying potassium dihydrogen phosphate and sweet and sour liquid to prevent plant premature aging, other management practices with conventional cultivation management. In the production process, it is generally preferable to regenerate eggplant flies two years ago. However, crops with severe verticillium wilt and bacterial wilt often do not advocate the use of this technology. China Agricultural Network Editor
