What is the correct way to control the high yield of vegetables?

In vegetable production, if the nitrogen fertilizer and water in the early stage of nightshade vegetables are too sufficient, resulting in excessive vegetative growth of vegetables, the manifestation is that the leaves are large internodes. The growth rate is fast. Poor ventilation and light transmission.

Severely affects the light. It is difficult to form flower buds. Reduce vegetable yields.

To put it in layman's terms, Wangchang is only long and does not bear fruit. That is, the stalks are thinner than normal, the nodes are longer than normal, the leaves are thinner, the color has changed, there are fewer flowers and fruits, and there are more flowers.

If the growth temperature of vegetables is too high, the respiration of vegetables will increase, the body's operation and physiological activities will be disordered, the plants will grow vigorously, the growth of plants and reproduction will be unbalanced, and the yield will decline. The leaf area of vegetable plants at the seedling stage is small, the transpiration is small, and the demand is also small, but the seedling root system is weak and the water absorption ability is poor. Therefore, it is necessary to maintain soil moisture, but not too much water to prevent seedlings from growing.

Water control, watering a lot when planting, and less watering for a period of time after planting, one can control the vigorous growth, and the other is to promote the rapid development of the root system. In the case of water shortage, the root system will go to a distance to find water, so the root system is developed. There are two main manifestations of vegetable growth, one is that the leaves grow too fast, which inhibits the growth of other parts including internodes.

The other is that the internodes grow too fast, inhibiting the growth of other parts of the body, including the leaves. Regardless of the type of growth, the impact on vegetables is very negative.

According to the requirements of different growth stages of vegetables, it is recommended to use balanced suspended carbohydrate water-soluble fertilizer combined with organic acid boron-calcium foliar fertilizer in the early growth stage of vegetables, which can be conducive to plant flowering and fruit setting. Suspended carb-water-soluble fertilizer with low nitrogen and high potassium type was used at the fruit expansion stage to improve the nutrients required for fruit expansion. After the emergence of seedlings and the time of seedlings.

In the 2 leaves and 1 heart stage of vegetable seedlings, the density of false planting was controlled at 120 130 plants per square meter. Nightshade vegetables were planted at the stage of 4 and 6 leaves, bean vegetables were planted at the stage of 2 true leaves, and melon vegetables were planted at the stage of 3 leaves and 1 heart of seedlings.

1. In the early stage of growth, it is necessary to start to control the prosperity, and there are more uniconazoles commonly used. In order to improve the effect of controlling the growth, many farmers increase the amount of the growth control agent, and control the trees to death at one time, and cannot resume growth for a long time, which is obviously not in line with the law of plant growth. 2. When many farmers use paclobutrazol to control prosperity, the concentration and time of use are not right, which not only affects the growth of crops in the current season, but also is difficult to decompose in the soil and inhibits the growth of crops, which is a point that we can't see.

Therefore, in order to achieve high crop yield and rational use of growth control agents, the requirements for farmers' operation are also very high.

When watering vegetables, you must control, do not water often, and control the fertilizer when fertilizing too much. Don't plant too densely during the planting process.

It is necessary to use spraying control agents, but it is necessary to pay attention to the correct selection of growth control agents according to the crop, and to prepare the relevant proportion and dilution, and to grasp the spraying period and cycle.

The level of vegetable yield, the core is the amount of vegetable photosynthetic product accumulation. If the photosynthetic products are sufficient, the vegetables will grow fast and have a high yield, while on the contrary, they will grow slowly and have a low yield. Where do the photosynthetic products of vegetables come from?

More than 98% of the photosynthetic products of vegetables come from the photosynthesis of leaves. In other words, in order to ensure the yield of vegetables, we must first ensure a reasonable number of leaves of vegetables.

Temperature control, fertilizer control, temperature control. Take the method of small water frequent watering, the amount of watering each time can not be too much, water thoroughly, and avoid flood irrigation.

That is, the vegetables grow too lush, and scientific methods are used to control the growth of vegetables, generally paclobutrazol, which is used on solid crops, such as peanuts, radishes, etc., and there are also water control fertilizers

<> vegetable control can generally use paclobutrazol.

Drugs such as chlormequatin. Vegetables are plants or fungi that can be used to make dishes and cook into food.

It is one of the essential foods in people's daily life, which can provide the human body with a variety of essential nutrients.

If you control Wang, you can let vegetables grow from vegetative growth to reproductive growth, which is very helpful for the improvement of vegetable quality and yield, and will not make vegetables grow, first of all, we must control the amount of fertilizer, do not use too much nitrogen fertilizer, and use some agents to control Wang.

Do not use a large amount of elemental fertilizer, be sure to grasp the time of fertilization, boron before flowering, calcium after flowering, silicon after flowering, and then be sure not to water too much, in a blooming environment, the temperature is not too high, and then be sure to reduce the time of light.

Mainly take leaves, Wangchang is not harmful to such vegetables, you can use to reduce the relative density of planting, and the leaves can be sprayed with 300 times of potassium dihydrogen phosphate, without hormone control. If it is a street vegetable, the relative nature of the natural environment is not easy to change, and the most frequently used method is to use organic chemistry to control the growth.

In the production of vegetables. If the supply of base fertilizer and water is too abundant in the early stage of nightshade vegetables, it will lead to excessive vegetative growth of vegetables. Its main manifestation is the long node position of the blade.

Faster growth. Natural ventilation has poor light transmission. Severely affects sun exposure.

Unable to produce flower buds. Reduce the amount of vegetables produced. From the beginning of transplanting, we should pay attention to the spacing between the vegetables, and in the case of using base fertilizer, apply more organic fertilizer and less fertilizer, especially less base fertilizer.

When planting vegetables, if the management methods are not timely, it is very easy to lead to the growth of vegetables. The vigorous growth of vegetables is very likely to lead to the vegetative growth of vegetables is greater than the growth of the reproductive system, resulting in the reduction of the nutritional value of flowers and fruits provided by vegetables, resulting in vegetable flowers, fruit drops and restless fruits, and the production of vegetables will be reduced, which is not possible. Watering floods during transplanting, and less watering for a period of time after transplanting, one can manipulate the vigorous growth, and the other is to promote the rapid growth and development of the root system.

In the case of a lack of water, the root system will go to distant places to find water, so the root system will flourish.

These two types of growth influence each other and promote each other. The key to the vigorous growth of vegetables is that the vegetative growth is too fast, such as too large leaves and too long nodes. This will directly affect the blooming of flowers and the hanging of fruits, so it is necessary to manipulate vegetative growth, which is what the questioner refers to.

Vitamins are supplemented according to the regulations of different growth links of vegetables. It is proposed to apply balanced floating carb water-soluble fertilizer combined with organic boron-calcium leaf fertilizer in the early stage of vegetable growth, which can be beneficial to the blooming and fruiting of green plants. At the fruit expansion stage, low-nitrogen and high-potassium floating carb water-soluble fertilizer is used to improve the nutrients needed for fruit expansion.

Reduce the amount of nitrogen fertilizer. Control watering. Carry out deep tillage to break the roots. It can play a role in controlling prosperity. The use of Sichuan production of Guoguang brand shrinkage and safety spray can play a certain role in controlling prosperity.

In vegetable production. Nightshade vegetables, if there is too much nitrogen fertilizer and water in the early stages, the vegetables will grow too vigorously. Its performance is the large internode length of the blade.

The growth rate is fast. Poor ventilation and light transmission. Severely affects the light.

It is difficult to form flower buds. Reduce vegetable production. From the beginning of the seedling, attention should be paid to the distance between the vegetables.

When applying basal fertilizers, organic fertilizers with higher decomposition rates should be used, and chemical fertilizers should be reduced, especially nitrogen fertilizers.

You can control the prosperity by reducing the use of nitrogen fertilizer, controlling the amount of watering, carrying out deep tillage and root breaking, or using professional spraying, ensuring a certain temperature in the vegetable greenhouse, reasonable top dressing, and reasonable sorting of branches and leaves.

You can control the amount of watering and control the fertilizer moderately, don't water too much, and don't let the outside temperature be too high. Growth regulators may also be used.

1. Put the shed for insulation. According to the variety of vegetables in the shed, adjust the closed tuyere and the time of the shed, when the minimum temperature in the shed is kept at 13 degrees, the shed can no longer be put for insulation.

When the temperature in the shed is relatively high, it is easy to cause the vigorous growth of the plants, and the methods of shading, irrigation, and interplanting of creeping vegetables can be used to cool down and control the vigorous growth of the plants.

2. Reasonable top dressing. Before planting, the land is fertilized, and fertilizers such as fully decomposed farmhouse manure are applied to meet the growth of plants. Nitrogen fertilizer is applied after planting and before fruit setting to prevent the plant from growing vigorously.

3. Leave fruit in a timely manner and prune reasonably. According to the growth of the plant, the fruit of the vigorous plant is left early. When the fruit is harvested, it can be delayed to reduce the flow of nutrients to the plant.

4. Control temperature, water and fertilizer. When the plant grows vigorously, it is necessary to reduce the night temperature in the shed, reduce the number of sprinkling, and control the amount of nitrogen fertilizer. At the same time, it can also be controlled by pesticides, such as 750-1000 times of boosting and controlling or 1500-2000 times of chlormequat spray.

When planting vegetables, we must fertilize according to the relevant proportions, it is best to use organic fertilizer, pay attention to the amount of fertilizer, and achieve the purpose after careful maintenance.

When preparing the land, turn the whole piece of land as deep as possible. It is recommended to turn the turn to a depth of 15 to 20 cm, which is conducive to downward rooting when vegetables grow. No fertilizer is applied when preparing the land, and only 3 5 cubic meters of straw are applied per mu. If the planting time is longer, the amount of straw can be increased to 6 10 cubic meters.

Control the temperature of the greenhouse to plant vegetables, according to the growth of the vegetables, if the vegetables have a vigorous situation, you can ventilate through the shed opening, reduce the temperature in the shed to control the growth of vegetables. Controlling the light and controlling the time of the light, some fruit vegetables will be differentiated in flower buds in advance, laying the foundation for the growth of female flowers, and more female flowers can prevent vegetables from growing.

1. Vegetables are planted in greenhouses, according to the growth of vegetables, if the vegetables have a strong growth potential, they can be ventilated through the shed opening to reduce the temperature in the shed to control the growth of vegetables.

2. It can be adjusted by controlling the moisture of the land. In general, watering a small amount of water can promote the growth of the root system, and watering a large amount of water can increase the growth of plants. Low soil moisture can control the growth of vegetables.

3. The application of seaweed fertilizer, calcium, iron, silicon, zinc and other trace element fertilizers on the roots and foliar surfaces can make the nutrients absorbed by vegetables turn to long flowers and fruits, and more flowers and fruits can control the vigorous growth.

Hello! For the types of vegetables that need to be controlled, including but not limited to the following:1

Old cucumber: Old cucumber is a ripe fruit on the basis of cucumber, so the growth rate is slow, but it is easy to Shandong after ripening, so you need to pick it in time and control its growth. Extended Supplements:

Old cucumbers need to maintain a suitable temperature and humidity during the growth process to avoid being affected by cold damage and rapid evaporation. At the same time, it is also necessary to fertilize scientifically and weed in time to maintain normal growth. 2.

Phaseolus vulgaris: The growth rate of vegetable beans is relatively fast, and it is easy to overgrow, which affects its quality and yield, and its growth needs to be controlled in time. Extended Supplements:

Phaseolus vulgaris needs to maintain proper soil moisture and light during the growth process to avoid the effects of flooding and hypoxia. At the same time, it is also necessary to pay attention to timely insect removal and fertilization to maintain normal growth. 3.

Cucumber: Cucumber has a short growth cycle and is prone to overgrowth, which affects its quality and yield, and its growth needs to be controlled in time. Extended Supplements:

Cucumbers need to be kept at the right temperature and humidity during the growth process to avoid being affected by cold damage and rapid evaporation. At the same time, it is also necessary to fertilize scientifically and weed in time to maintain normal growth. Therefore, in order to obtain a healthy vegetable yield, it is necessary to control the growth rate and growth rhythm of vegetables in time to maintain a normal growth state.

Hello!

It is not uncommon for the growth of vegetables to be controlled. Some varieties of vegetables are able to grow lush foliage quickly during growth, and these parts will take too much nutrients and water and cannot be effectively converted into the fruit. In addition, excessive growth will also suppress the plants, causing them to produce smaller fruits.

In order to control the growth of vegetables, you need to try to find varieties that have been optimized before planting, and it is best to be able to monitor the growth status of the plants in the daily planting process at the right time, so as to adopt the right strategy to control the growth of the plants. Some of the vegetables that need to be grown under control are: celery, carrots, eggplant and watermelon.

In these plants, you can control their growth through different methods, such as foliar irrigation and pruning. Foliar irrigation is done by spraying the leaves of plants so that they are controlled by water and nutrients. This method is very effective in controlling the growth of vegetables.

This method can be done by submerging the leaves of the plant in water or spraying it with a watering can to meet the plant's nutrient needs. Pruning is another common method of controlling the growth of vegetables. By pruning the foliage of the plant, you can make the growth direction of the plant more rational and reduce the stress on the plant caused by the remaining foliage.

This also results in healthier plants and higher quality fruits. Therefore, controlling the growth of vegetables is very important to ensure a good harvest and reduce waste. Through irrigation and pruning, we can help vegetables better transform nutrients and grow better.

Many vegetables grow luxuriantly during the growth process and need to be controlled. Here are some common vegetables that need to be grown or pruned with control1Tomato:

Colonization and cuttings are required, pruning and budding in a timely manner. 2.Cucumber:

Side branches, vines, and side buds need to be pruned frequently3Pumpkin: Growth needs to be controlled, the tips are cut off and the side branches are pruned.

4.Eggplant: Colonization and cuttings are required, and vines and side buds are frequently pruned.

5.Peppers: Planting and cuttings are required, and tips and side branches are often cut off.

6.Cauliflower: It is necessary to control the growth, and prune the side buds and flower alcohol when the number is high7

Broccoli: Leaves and buds need to be pruned in time to maintain nutritional balance.
