The recent zucchini management control is the focus
When interviewed by Feng Jiacun, Gaoliu Town, Qingzhou City, the reporter saw that the growing of the vegetable sheds in the sheds was generally prosperous and that the plants were sitting on them.
Asked why, many vegetable farmers told reporters: “In the past, the weather forecast said that this year is a cold winter. We want to rely on temperature control to control the growth of plants and prevent leggy. If we use plant growth regulators, it is likely to seriously affect Because of the growth of zucchini, there was no use of regulators. However, unexpectedly, although outside temperatures were not high this year, the weather was fine and the temperature inside the shed was high, resulting in a serious growth of the zucchini.â€
So how do you judge whether or not the zucchini is prosperous? To determine if the post-harvest squash is growing, the two or three leaves near the growing point should be observed. When farmers discovered that the two new leaves around the growing point of zucchini stretched more, and the angle of opening with the main trunk was appropriate, and the height of the leaves was the same as that of the surrounding old leaves, the leaves were slightly yellow and showed strong growth, indicating that the plant grew normally. . When the plant growth spot has three leaves and one heart, or the opening angle of the two leaves and the trunk around the growth point is small, the new leaves are significantly higher than the surrounding old leaves, indicating that the plant appears prosperous. Therefore, the farmers should take measures when the growing point has just shown a prosperous situation.
Controlling plant growth should be based on temperature and humidity control combined with plant growth regulators. There are many kinds of agents that can inhibit the growth of squash, such as chlormequat, co-prime, paclobutrazol, etc., but the most effective one is paclobutrazol.
Farmers can spray 6 grams of paclobutrazol into a bucket of water, evenly sprayed on the middle and lower leaves of the plant, and must not spray the liquid onto the upper leaves of the plant to prevent phytotoxicity and severely inhibit plant growth. If the liquid is to be sprayed on the middle and upper leaves of the plants, the use of paclobutrazol can be reduced to 2 g and 550-650 plants per barrel can be sprayed. The vegetable farmers must pay attention to watching the weather forecast and ensure that there are more than 3 days of sunny days after spraying to prevent the occurrence of phytotoxicity, excessive control of Wang and affecting the normal growth of plants.
