Greenhouse peppers focus on prevention and control of growing uneven

In the spring, the maximum temperature in the outside world rose above 15°C. When the weather was fine, the temperature in the shed kept high and the plants grew very quickly. Recently, the reporter saw in the shed of Master Liu, a vegetable farmer in Xiliuying Village, Datian Township, Shouguang City, that the sharp peppers in the shed were uneven and the plant growth was different. One third of the trees in the line were taller than other plants. More than ten centimeters, there is a clear trend. There are also some trees that are short because of early fruit setting and weak roots. In the spring, many farmers will have such problems in their sheds.

The reason why there is a prosperous growth is that on the one hand, the weather is fine in recent days and the temperature in the shed has been maintained at a relatively high temperature. On the other hand, this period is the expansion of the sharp pepper fruit, and the water and fertilizer supply is relatively sufficient. After the child was removed, the burden on the plant was abruptly reduced, nutrients were abundantly supplied to the growth of the leaves and stems, and thus the internode elongation and the large and green leafy growth were observed. Prosperous plants that are very prosperous have a great influence on flowering and fruit setting, and are easily trapped in a vicious cycle. Those low plants, because of the obstruction of other tall trees and the competition of soil nutrients, are in short supply of nutrients and growth is always slow, making it difficult for the plants in the greenhouse to grow in consistency.

The uneven growth of plants has a great impact on the overall yield. Therefore, as the temperature rises, it should pay more attention to controlling the phenomenon of uneven growth of vegetables.

First of all, prosperous trees should be controlled individually. Farmers can use 500-fold booster or 2,000 times more love, spraying small plants with a small watering can, inhibiting their growth. If the plants fall seriously, use 2% naphthalene acetic acid 6000 times spray. It should be noted that it is best to use a small watering can to point to avoid a large number of agents falling on other plants.

Second, adjust the plant to set fruit. For plants with prosperous tendencies, adequate fruit should be maintained to ensure the balance between reproductive growth and vegetative growth. For low plants, fruit should be kept as little as possible to promote vegetative growth.

Again, increase the exposure time and increase the temperature difference between day and night. In the afternoon, it is necessary to postpone the shed, increase the illumination in the shed, and increase the temperature difference between day and night to reduce the consumption of organic materials at night and avoid excessive growth of the plants' nutrition. During the day, the temperature is controlled at about 25°C, and it drops to 13°C at night. The amount of water and fertilizer should be adequate, and the amount of water and fertilizer should not be increased in order to enlarge the fruit, so as to ensure sufficient nutrients in the soil.

In addition, closed fields and poor air and light transmission are also factors that cause prosperous growth. Therefore, pruning should be strengthened to remove redundant side branches and old and sick leaves, especially internal litchi, and improve ventilation and light transmission conditions. Prosperous.
