Although greenhouse cultivation is currently a hot planting method, there are still many shortcomings when planting vegetables. Insufficient care will affect the normal pollination of vegetables. Therefore, vegetable farmers generally carry out flowering and flowering work. The following small series will be detailed to everyone. Talk about the cultivation of green flowers in greenhouses.
Vegetables grown in greenhouses often suffer from lack of light, temperature and humidity, and they cannot be pollinated properly. Correct application of 2,4-D, anti-dropping and other flower and silk flowers can improve the fruit setting rate, accelerate the fruit expansion, and add the output value. However, if you do not pay attention to certain details, it is very simple to affect the plant, such as the deformation fruit. Lead to production cuts, etc.
How to choose ankle flower
Both 2,4-D and anti-fallin can be used for solanaceous vegetables. It has been shown that 2,4-D is applied and the fruit setting rate is high, but there are certain damages to the young shoots and young shoots of the solanaceous vegetables. Therefore, it is generally used for decorating flowers or altering flower handles; while the anti-falling agent is very lightly damaged on the young shoots of vegetables, and the dosage is appropriate and there is no damage, and it can be sprayed with flowers, saving labor and labor, safe and useful, but the ratio of fruit set is 2,4-D is lower.
Practice has proved that the choice of which anthers should be based on the growth of the plant. For plants that are too strong or too weak, it is recommended to use 2,4-D to extract flowers. For medium-sized plants, it is recommended to use anti-fallin.
So how do you distinguish the strength of the plant?
Generally, the plant stems are thick and thin, the leaves are large and thick, the leaves are dark green, and the plants with more water content in the stems and leaves are stronger; the stems are fine and thick, the leaves are small and thin, the leaves are yellow-green, and the stems are yellow The plants with less water content in leaves have weaker growth; the stems and stalks of the plants are uniform and uniform, the leaves are flat, and the leaves are green and green, indicating that the growth is moderate.
Do not spend too early
Many vegetable farmers who grow tomatoes have a very early flowering point. They only need to have flowers to make a point. They often have poor flower bud differentiation at the top of the list. Even if they live, they will develop into deformed fruit in the later stage.
Suggestion: Vegetable seedlings should be based on strong trees. Don't leave fruits too early. For example, in the process of cultivating autumn sorghum tomatoes, the top spikes can be removed to prevent the later deformation of fruit, and it is beneficial to strong seedlings.
About cucumber, you can start melon with more than 12 leaves. From colonization to production, it is best to control it in the high temperature season for 35 to 40 days, late autumn and early spring for 40 to 45 days. By leaving the fruit late, the flower is late, so that the nutrients are more supplied to the root system. And stems and leaves grow, cultivate strong trees. It is not advisable to use sputum flowers because the "small yellow spots" on the leaves of cucumbers are particularly severe (ie, cucumber target spot disease) because there are currently no drugs that are particularly useful for the disease.
It is learned that the price of cucumber has been high recently. In order to take more fruit, the flowers on the plant are all smashed, but I did not expect the plant to grow poorly, and the resistance to the disease is reduced, leading to the agile conveyance of "small yellow spots".
Suggestion: How much should be determined according to the growth of the plant; if the plant grows weakly, the vegetable farmers should try to reduce the amount of melons, first raise the stems, do not let the nutrients supply reproductive growth, and the leaves of the plants are poorly developed, leading to multiple diseases.
It is very important to make the anthers in the test. Some vegetable growers make their own anthers. Because the 2,4-D products of the new manufacturers have been replaced, if they are still manufactured according to the original concentration, the eggplants that are pointed out show a lot of dead fruits. It constitutes a serious loss.
Suggestion: Do not arbitrarily participate in hormone-containing foliar fertilizers in the anthers, and change the concentration of the drug at different temperatures. However, when changing, you must first do a small-area test. As long as the test is successful, it can be used in a large area to prevent the formation. huge loss.
Best time to spend
It is possible to start the flower when the top flower of the top flower is 2 to 3 flowers open. When the flower petals of the female flower are completely opened, and the flower is elongated to the bell mouth, the flower is most suitable. It is easy to form a stiff fruit too early, and it is easy to form a cracked fruit too late.
Do not point to the stigma liquid directly affects the stigma easy to present cracking fruit, especially when the repeated flowering is severe, it simply constitutes a failure. Pay attention to the soil moisture If the soil in the shed is too dry, you should first sprinkle the water and then flower it to prevent the sprinkling of water after the flowering.
Point flower and management
The flower of the first flower of each inflorescence is simply transformed, and should be removed before the flower is spent. After fruit setting, the fruit grows at an accelerated rate. It is necessary to release the wind and drain in time, strengthen the management of water and fertilizer, and do a good job in pest control.
Precisely grasp the time spent
The time when the hormone is used to treat the flower is only 3 days, that is, the day of flowering and the day before the opening, the early treatment is easy to form a rigid fruit, and the rate of fruit set is reduced afterwards. It is best to choose the day when the eggplant flowers are all purple and open.
Rationally adjust the growth of plants
Plant growth is too weak, too strong will affect the hormone treatment. The pedicels of the weak plants are thin and thin, and it is very simple to suffer from hormone treatment. Plant nutrients grow too prosperous, inhibit reproductive growth, and also affect hormone treatment. Therefore, when planting, you should select strong seedlings, plant appropriate seedlings after planting, and control the water and fertilizer and temperature to balance nutrient growth and reproductive growth.
The flower bud flower is actually used to allow the planted greenhouse vegetables to be properly pollinated, so as to increase the vegetable production value. Don’t look down on the plantation management of the flower buds. If the vegetables you want to grow can be high-yield, you have to learn the small series. Share the point flower tricks. The above method hastened to collect.
