Cutting stubble Regeneration cultivation technique of eggplant Seedling

It has been proved by many years practice that the regeneration culture of eggplant seedling cutting is an effective measure to increase yield, reduce production cost, increase economic benefit and adjust the light and peak season of eggplant.

1. Stubble cutting period

Eggplant in spring and autumn is the price of high and low yield, and into midsummer is the period of high yield and low price. Therefore, summer is the best time to harvest eggplant seedlings. In addition, eggplant has a main root eggplant, door eggplant, four-sided fighting eggplant fruit growth large and fat, eggplant seedling upper eggplant fruit small and thin, not welcomed by the market characteristics. And through cutting seedling regeneration, just put the high yield and low price period back 30 - 40 days, in the market lack of eggplant, cutting seedling regeneration eggplant is just high yield and high price period, so eggplant high yield and low price period is the best cutting seedling period.

2. Method of cutting seedlings

There are two kinds of eggplant seedling cutting: low stubble seedling cutting at 10 cm of trunk on the ground and high stubble seedling cutting on the eggplant. In the early stage of high yield and low price, it is generally used to cut seedlings with low stubble, which can postpone the fruiting period for more than 40 days, and the eggplant fruit is large, high yield and good benefit. High crop cutting is at the late stage of high yield and low price, and the fruiting period can be postponed for more than a month. The fruit is small and the yield is low. Therefore, low crop cutting is generally adopted. However, some vegetable farmers see that eggplant seedlings grow luxuriantly, yield is high and reluctant to cut seedlings, often miss the appropriate time to cut seedlings, so they have to cut seedlings with high stubble.

It is better to cut seedlings into oblique stubble with fruit branch shears for fruit trees. After cutting, apply 500 times solution of 50% carbendazim or methyl thiophane solution on the cut mouth to prevent wound infection. It is best to dry all cut wounds and then apply lead oil to prevent wounds from losing water and improve survival rate. 5-6 days after shearing, buds can be sent out under shearing, 2-3 strong buds are selected and retained, and the rest are broken off in time. Only one bud is left on the branches of high stubble cutting seedlings, and redundant buds are removed in time. After cutting, the germination rate of eggplant seedlings is generally 80%-90%, and the number of seedlings remaining in 667 square meters is about 3000. Solanum seedlings are too dense, branches and leaves are luxuriant, and the light receiving conditions are not good, which is easy to cause physiological diseases of some fruits, such as hollow fruits and albino fruits, etc., and the diseases and insect pests are seriously damaged, thus reducing the yield and benefit.

3. Management after stubble cutting

10-15 days after stubble cutting, weeding and soil cultivation are carried out once, urea and potassium dihydrogen phosphate are applied to 667 square meters 10-15 kg respectively, and sufficient water is irrigated once in drought. The regenerated eggplant can be harvested and marketed 35-40 days after cutting. After the first harvest, irrigation and topdressing are applied once more. At the same time, attention should be paid to the prevention and control of pests and diseases. At this time, the main pest is tea yellow mite, which can be controlled by mite net or Aifuding. There are also 28 star ladybugs, which can be controlled by trichlorfon. The main disease was Verticillium wilt, which could be irrigated with 500-600 times solution of 75% thiophanate-methyl. 50~ 75g of liquid medicine was applied to each plant, and it had good control effect after 15 days. In the fruiting period, spraying 500 times of disinfectant alum once every 7-10 days, spraying 2-3 times continuously, can prevent cotton rot well.

The harvest period can be prolonged by 15-20 days and the yield and benefit can be increased by keeping the stubble seedlings in cold shed before the initial frost stage.

Cutting stubble regeneration of eggplant seedlings reduces seedling raising links, saves seeds, saves labor and time, and is beneficial to crop rotation. Because the root system of adult eggplant seedlings is developed, the disease resistance ability is enhanced, the disease is few, and the new branches grow vigorously. As long as timely scientific management, we can obtain better economic benefits.
