Tomatoes are the fruits and vegetables that people often grow. I think everyone must have encountered a lot of tomato diseases when planting them. So, do you know what is going on? If you don't know, you can follow the small series to see how to prevent it. In China, the planting area of ​​tomatoes is increasing, and the variety is increasing. We can eat tomatoes almost all year round. However, various diseases in the growing process of tomato growing in greenhouses or on land are gradually emerging. Among them, tomato hibiscus is one of the hazards affecting the quality and yield of tomatoes. First, the symptoms of tomato wood fruit The main manifestation is that the peel of the tomato is hard, the fruit is small and the fruit shape is not square. The surface of the fruit has brown spots and cracks of different shades. The tomato fruit is mainly caused by the lack of boron in the plant. Second, the reasons for the frequent occurrence of Hetaomu suppository 1. Long-term use of chemical fertilizers leads to acidification of soil and loss of boron in the soil. 2. Some vegetable farmers prefer to use lime to treat the soil when changing the mash. Excessive application of lime in the soil may cause boron deficiency. 3. The lack of organic matter in the soil leads to the loss of boron in the plants. 4 Excessive application of potassium fertilizer results in limited absorption of boron by plants. 5. The tomato plants grow prolonged under high temperature conditions, and the mobility of boron in the plants is poor. Boron cannot be timely and fully distributed to the urgently needed parts, resulting in local boron deficiency. Third, how to prevent tomatoes from appearing 1. Rational fertilization to prevent soil acidification or alkalization. The Fugen biological fertilizer or the base fertilizer can be used to adjust the soil, and the chitin, alginic acid and microbial agents can be rationally applied to improve the soil. 2. If there is boron deficiency in the soil, organic fertilizer should be added. It can fertilize the soil to promote the expansion of the root system while strengthening the absorption of boron by the root system. 3. Reasonable watering. The principle of watering is to ensure the water supply of the plants and prevent the soil from being too dry or too wet, so as not to affect the absorption of boron by the roots. 4. Regularly spray 750-1500 times of calcium boron on the plant spray to prevent boron deficiency. The occurrence of cork formation in tomatoes is a common phenomenon. Most of them are due to lack of nutrients and nutrients, and lack of boron. Therefore, you must pay attention to planting, otherwise it will seriously affect the quality of tomatoes. double chaise lounge,Chaise Lounges,leather lounge chaise Guangzhou LoPhiDa Co.Ltd , https://www.guangdongwidinlsa.com
