As spring comes, the highest outside temperature rises. When the weather is fine, the temperature in the shed is kept high, and the plants grow very quickly. At this time, the peppers in the greenhouse are easy to be uneven, and the growth of the plants is greatly different. Even one-third of the plants in a row are more than twenty centimeters higher than other plants. Some plants are shorter because of early fruit setting and weak root systems. In the spring, many vegetable farmers have such problems. The reason for the long growth is that on the one hand, the weather is fine and the temperature in the shed has been maintained at a high temperature. On the other hand, this period is the period when the pepper fruits are inflated. Suddenly, the burden on plants was reduced, and nutrients were supplied to stems and leaves for growth, resulting in internode elongation and large, green leaves. For the long and severe plants, the flowering and fruit setting are greatly affected, and they easily fall into a vicious cycle of blind growth. For those low plants, because of the shelter of other plants and the competition of soil nutrients, the nutrition supply is insufficient, and the growth is always slow. It is difficult to make the plants in the shed grow uniformly. The uneven growth of plants has a great impact on the overall yield, so as the temperature rises, more attention should be paid to controlling the growth of hot pepper. First, long plants need to be controlled individually. Vegetable farmers can use Zhuangsu 500 times or 2,000 times more love, use a small watering can to spray the top of the growing plants to suppress their excessive growth. If the plants have severe flowering, they can be sprayed 6000 times with 2% naphthaleneacetic acid. It should be noted that it is best to use a small watering can to point to prevent a large amount of chemicals from falling on other plants. Second, adjust the fruit set of the plant. For plants with a strong growth trend, it is necessary to retain more fruits appropriately to ensure the balance between reproductive growth and vegetative growth; while for low plants, keep as few fruits as possible to promote their vegetative growth. Again, increase the time to see the light and widen the temperature difference between day and night. Sheds should be postponed in the afternoon, increase the light in the shed, and increase the temperature difference between day and night, reduce the consumption of organic matter at night, and avoid excessive plant growth. The temperature is controlled at about 25 ° C during the day and dropped to 13 ° C at night. The amount of water and fertilizer should be supplied in an appropriate amount, and the amount of water and fertilizer should not be arbitrarily increased in order to expand the fruit, and sufficient nutrients in the soil can be used. In addition, closed fields and poor ventilation and light transmission are also factors that lead to long growth. Therefore, it is necessary to strengthen the pruning and remove the extra side branches and old diseased leaves in the row, especially the internal bore branches. Improve the ventilation and light transmission conditions, and can also inhibit Prosperous. Disclaimer: Some articles on this website are transferred from the Internet.
