Beans grow only vines and do not bloom. What's going on?

Beans are common legume vegetables that bear pods in summer. when they are planted in the southern spring, farmers will basically plant some at home, and some nights will be planted on a certain scale for sale, but the most common problem in planting beans is that they only grow vines, do not blossom, and cannot receive pods without flowering, no yield, or low yield, so why, how should we prevent, adjust and improve this situation? Let's take a look now!

First, reasons

The nutrition of water and fertilizer is too sufficient, causing the vines to grow madly and grow only, so they do not enter the reproductive growth and stay in the vegetative growth link all the time, so they cannot blossom; if the open field is planted too early, the temperature is relatively low or when it is suddenly cold in spring, it will inhibit the growth. similarly, if the plant is planted too late, it may not be able to blossom in the event of high temperature during flowering. If you use too much nitrogen fertilizer, you should apply more scale fertilizer and spray some growth regulators, such as Yumar fruit protection; or it is because of insufficient nutrition and moisture, the planting soil is too barren, and the plant has no nutrition for flowering, so it is possible to produce insects in the early stage and use too many pesticides. If you cause drug damage, you won't be able to bloom.

II. Prevention and improvement

1. Fertilizer application

Early growth should be fertilized, but do not use too much, enough normal growth can, see the overgrowth, the heart to pick the heart, sparse part of the branches, do not leave too many extended branches.

two。 Temperature

Sowing to choose an appropriate period, to be above 12 degrees before you can start sowing, seedling emergence temperature above 15 degrees is the best, the best temperature during the growth period is between 18 and 28 degrees, more than 35 degrees slow growth, less than 5 degrees growth stopped. Therefore, when sowing, it is also necessary to roughly calculate what environment the various stages will be in, as far as possible.

3. Nutrition

In the early stage of growth, we should pay attention to nutrition, choose fertile, high-organic soil to plant good nutrition, if the soil conditions are not, we should find ways to improve the planting field, such as digging up the original soil, using humus soil, mixed with river sand, peat and so on to plant nutritious soil. Spraying Yumalebao regulates the hormone balance in the plant and contributes to flowering.

4. Less medicine

When preventing pests, we should pay attention to the use of pesticides that can be trapped and artificially killed as far as possible, pesticides can be used with new types of less harmful pesticides, do not use EC as far as possible, the pollution is relatively large, or do not use contact insecticides, which can be easily absorbed by plants.

Beans do not blossom, not too much fertilizer in the early stage, too much nitrogen fertilizer, lack of nutrition, or the direct impact of temperature. In addition, pesticides have caused drug harm, in fact, there may also be some reasons for other production, and it is necessary to accumulate more experience in production.
