Eggplant cracking is a common disease in eggplant production. Both eggplant and eggplant can occur, and it is most common to approach mature eggplant. Eggplant can be cracked in various parts, cracks of different sizes, some of the seed valgus exposed, and after the cracking of the fruit susceptible to bacterial infection caused by rotten fruit, seriously affecting product quality and economic benefits. First, the cause and symptoms of cracking 1. The cause of tea cracking is tea crackers. After the tea plant has damaged the eggplant, it causes the peel to be rough and the rough part to stop growing, while the pulp continues to grow, causing the fruit to crack, the grain to be exposed and the fruit bitter. Abnormal growth of the plants, the young leaves of the eggplant become smaller and curled, the leaves become thicker and stiffer, the back of the leaves turn brown, and there are oily luster. 2. Cracks are caused by uneven water supply. Breaks caused by uneven water supply are mainly on the top of the longitudinal cracks, exposing the seeds. In the process of eggplant cultivation, the water supply is uneven, and the drought suddenly occurs. Especially in the early stage of eggplant expansion, it encounters a long period of drought. After sudden sudden flooding or sudden rain, the fruit grows rapidly and the pulp expands faster than Peel, peel is broken, causing cracking. The plants performed normally. 3. When the flower buds are differentiated, the temperature is low and cracking occurs. Eggplant flower bud differentiation temperature is low, especially at night when the temperature is low, easily differentiated into multi-ventricular malformation flowers, flowers developed from the fruit often show top cracking, under normal circumstances the plant performance is normal. 4. Cracking caused by improper hormone treatment. When hormones are used to decorate flowers or flowers, if the concentration is too high or the high temperature at noon is used or repeats the flowering or flowering, the fruit may be deformed and top cracking may occur, and the plant performance is normal. However, when silkworms or flowers are applied, if the hormones hit the young leaves or growing points, the top leaves of the plants will shrink and shrink. Second, preventive measures 1. Timely prevention and treatment of tea-yellowing. In the middle and late stages of eggplant growth, the peak period of the yellow tea was occurred, and low-toxic, high-efficiency and low-residue pesticides should be used for prevention and control. Tea scutellariae mainly concentrate on the back of young leaves, so when spraying acaricides, it is necessary to pay attention to spurt young tender parts, especially the back of tender leaves. Can be used 1.8% Qi Qi prime EC 3000 times, 73% Kotel EC 2500 times and other spray, spray every 7-10 days, and even spray 2-3 times. 2. Water supply should be balanced. During the growth of eggplant, the water supply is appropriate. During the flowering period, the water supply must be balanced and avoid sudden changes. In particular, the fruit should not be drunk after a period of fruit expansion. If the eggplant is cultivated in open field, it will be drained in time if it encounters heavy rain and heavy rain in the early stage of fruit enlargement. 3. Strengthen the temperature management during flower bud differentiation. The 2-6 leaf stage is the flower bud differentiation period of eggplant. The temperature management in this period should not only consider the vegetative growth of seedlings, but also consider the temperature requirement of flower bud differentiation and development. The temperature is too high to cause seedlings to grow, and the temperature is too low to affect flower bud differentiation. For this reason, in the temperature management, it is best to control the temperature at 27°C-30°C during the day and 18°C-20°C at night so that the seedlings can grow vigorously and promote the flower buds. Normal differentiation and development. If the nighttime temperature is below 12°C for a long time, abnormal flower bud differentiation will occur. 4. The correct use of hormone treatment. When using hormones to decorate or spray flowers, be sure to follow the drug instructions for dispensing and handling. Avoid hormone treatment at high temperatures at noon, and do not repeat flowering or spraying. When the flowers are sprayed or sprayed, the concentration may be lower when the temperature is high and the temperature is low when the temperature is appropriate.
