Latest Key Points of Zucchini Fruit Management Techniques
Zucchini is a very popular vegetable and can basically be grown all over our country. When growing zucchini, if you want to improve the yield and quality of zucchini, then management work is very important. In particular, fruit management must be done well to ensure the normal growth of zucchini. So how should zucchini fruit be managed? Today, the editor will bring you the fruit management of zucchini. Let us take a look together below!
1. Hormone-based fruit retention
When we grow zucchini, zucchini sometimes shows flower and fruit drop, so we should pay attention to doing a good job in fruit retention. Among these, the most common method of fruit retention is hormone-based fruit retention. Reasonably use hormones for fruit retention when the amount of faded zucchini flowers reaches about 2/3 or so. Spray an appropriate amount of a mixed liquid such as urea and monopotassium phosphate for fruit retention. Generally, spray once about every half a month, and its fruit retention effect is still very obvious.
2. Fruit thinning and bagging
In addition to doing a good job in fruit retention, we should also pay attention to proper fruit thinning to avoid too many fruits hanging and exceeding the load of the plant. When thinning fruits, we should focus on removing diseased fruits, deformed fruits, small fruits and some densely set fruits that are growing too closely. The number of fruits retained should be controlled according to the leaf-to-fruit ratio, and attention should also be paid to determining it according to the variety. For example, some varieties retain one fruit for about 50 leaves, while others need about 100 leaves. After fruit thinning, pesticides such as Lvjing and carbendazim should also be used for sterilization and insect control, and then proper bagging should be carried out to ensure normal fruit growth.
3. Reasonable fertilization
Besides this, we should also pay attention to doing a good job in fertilization. In particular, attention should be paid to the application of fruit-stabilizing fertilizer and fruit-strengthening fertilizer. Usually in May each year, fertilization should be carried out according to the tree vigor. If the tree vigor is weak and the number of flowers is large, then fertilizer should be applied to the soil once. The fertilizer should be mainly phosphorus and potassium fertilizer to alleviate physiological fruit drop. Then apply fruit-strengthening fertilizer to provide sufficient nutrition for the growth of zucchini. If the fertilizer is insufficient, then the growth of zucchini fruit will very easily show phenomena such as small fruits and deformed fruits due to insufficient nutrition, affecting the yield and quality of zucchini.
4. Pest and disease control
When it comes to fruit management, pest and disease control work is naturally indispensable as well. Among them are common longhorn beetles, leaf spot disease and so on. We should strengthen management, frequently observe the growth of zucchini, and ensure the normal growth of zucchini. At the same time, we should do a good job in fertilizer and water management, and must not overwater or overfertilize, so as to avoid fertilizer damage and waterlogging damage. This can trigger the occurrence of pests and diseases. When zucchini shows abnormal conditions, the specific cause should be found out in time, and then corresponding control should be carried out to avoid the spread of the disease.
