After the regeneration of the old plants, pepper, eggplant and tomato have significant yield-increasing effects, and the harvest season after regeneration is the off-season of fruit and vegetable production, with high prices and doubled benefits.
For the regeneration of old plants, the plants are required to have a strong ability to regenerate. In the first half of the retreatment, the fertilizer should be applied with 15 kg of ammonium nitrate, so that the soil maintains sufficient fertility and promotes early sprouting of the roots. The regeneration treatment time is also very important, and should be carried out when the plant fruit is basically harvested and the base sprouts have sprouted. Too early, the sprouts are small and grow slowly; too late, the sprouts grow too high, and they tend to grow into high-stem seedlings, which has a greater impact on later yield. The old plants in the field were removed, and a strong seedling was selected for each hole, and the remaining seedlings were all removed. Second, we must prevent the occurrence of diseases. It can be sprayed once every 7 to 10 days (10-20) X10 of 920 or 10 (K) times methyl tobrahim. Because the regeneration of new seedlings is in the high temperature and rainy season from July to August, the seedlings grow too fast and are prone to madness. 50% of the short-straining 200~2500 times solution should be sprayed according to the situation to control growth and cultivate strong seedlings. The foundation for high yield in the later period was laid. In the early stage of the bud, in order to increase the output, water should be added, and then 15 kg of ammonium nitrate should be applied. If necessary, some organic fertilizers can be properly applied. Pest control is the same as in the previous period.
In addition, for the fields of severe defoliation, falling flowers, fruit drop, no harvesting and production value caused by pests and diseases, the old plants can be regenerated early, in the same way as above.
