Prevention and cure of eggplant physiological diseases in greenhouses

The eggplant cultivated in the greenhouse, the results of the initial positive value of low temperature and low light period, prone to various physiological barriers, according to its causes should take the appropriate prevention and control measures:

1, yellow leaves. The young leaves are bright yellow-white with green leaves on the tip and rust stains on the middle and lower leaves; more fertilizer, high humidity, excess soil acidity or manganese nutrients, inhibition of ferritin absorption, etc., easily lead to new leaf yellowing. Prevention and control measures: After onset, spray 500 times ferrous sulfate on the leaf surface (do not overweight); apply magnesium hydroxide and lime in the field to adjust soil pH; supplement potassium to balance nutrition and meet or promote

Ferrite supply.

2, buds are not open. The ovary does not inflate and the buds do not open tightly, affecting pollination and fertilization. In the cold season, when there is water shortage and the air is humid, the pH value of the soil is above 7.5, and the effectiveness of boron in the soil is reduced. Excessive lime and calcium in the field and induced boron deficiency in plants can cause buds to remain open for a long time. Control measures: spray borax 700 times or amino acid polypeptide pollinator on leaf surface.

3, fruit cracked. The fruit is stiff but not inflated, the skin is dull, and there are white stripes. After watering, it becomes cracked and it grows little. After the eggplants are tethered, they will crack the fruit after being watered on sunny days. Prevention and control measures: During the later period of planting, pure phosphorus is applied for 2 to 3 kg per mu; during the final stage, potassium fertilizer is mainly applied.

4, fallen fruit. In the low-temperature period, the lower leaves yellowed off and the young fruit in the high-humidity period softened and fell. When the temperature is too low, nitrogen and phosphorus fertilizers are applied excessively to make the soil concentration large, and the plants will be aged due to long-term nutrient imbalance, which is the sequelae of the reduction of gibberellin production caused by zinc deficiency. The petiole and culm, stalk, and fruit junctions were separated and fell off due to lack of auxin. Control measures: Aged eucalyptus leaf surface sprayed with 700 times of zinc sulfate, or 1 kg of zinc sulfate per acre, can also be sprayed on the surface of the leaves and Other zinc-rich nutrients to prevent long-term growth.
