Can I spray cucumber with vinegar and sugar?

Vinegar contains acetic acid and has a certain bactericidal effect, so spraying vinegar with white sugar on cucumber can increase the acidity of cucumber leaves, inhibit the growth of bacteria, and control diseases and insect pests that are not suitable for acidic conditions. and vinegar and sugar contain a variety of nutrients, which can not only increase the yield of cucumber, but also improve the quality of cucumber.

I. the effect of spraying cucumber with vinegar and sugar

1. prevention and control of diseases and insect pests

The main results are as follows: (1) according to the experiment, the bacterial diseases and virus diseases in cucumber are suitable to reproduce and grow under neutral or alkaline conditions, and the main component of vinegar is acetic acid, which has a certain bactericidal effect.

(2) after spraying vinegar solution on cucumber leaves, it can increase the acidity of cucumber leaves, and then inhibit or kill diseases and insect pests that are not suitable for acidic conditions, so as to achieve the effect of control.

(3) it can not only act on cucumbers, vinegar and sugar can also have a good effect on the control of virus diseases of tomato and pepper and soft rot of Chinese cabbage.

2. Increase the output

According to the experimental results, during the period from planting slow seedlings to flower bud stage, cucumber was sprayed with vinegar and white sugar solution every 7 days for a total of 3 times, which could increase cucumber yield by 10% and 35%.

3. Improve the quality

Vinegar in addition to acetic acid, there are amino acids, succinic acid, lactic acid, glycerol and other nutrients.

When vinegar is sprayed on the leaves of vegetables, these nutrients are absorbed by the leaves, which can increase the internal nutrition of the plant, accelerate the formation of chlorophyll, improve the photosynthesis of cucumber, and thus improve the quality and characteristics of cucumber.

Second, the knack for high yield of cucumber

1. Amount of fertilizer applied

The main results are as follows: (1) if cucumber wants to keep high yield, the amount of base fertilizer is very important. first, it is necessary to ensure that the nutrition of base fertilizer is comprehensive to meet the nutritional needs of cucumber in the whole growing period.

(2) to ensure the quick and long-term effect of base fertilizer, the base fertilizer should not only meet the growth needs of cucumber seedlings, but also meet the nutritional needs of cucumber in the middle and later stage. only in this way can the premature senescence of cucumber stems be avoided.

2. Proper watering

The main results are as follows: (1) there are two key times for cucumber watering, one is pre-planting water and the other is planting water.

(2) the water before planting is watering once after adjusting the row spacing of cucumber planting, so that the planted land can absorb enough water, so as to ensure that after cucumber seedlings are planted in the future, there is enough groundwater in the depths of the soil to allow cucumber seedlings to tie down.

(3) planting water is to dig holes and then bury seedlings, and finally irrigate planting water. The planting water advocates watering thoroughly, and only pouring through the planting water can make the seedlings closely combine with the surrounding soil and avoid air raids, which is conducive to the introduction of roots and the cultivation of strong seedlings.

3. Use drip irrigation

The use of drip irrigation can turn cucumbers into an integrated irrigation mode of water and fertilizer, which can save water and fertilizer, stabilize soil temperature, ensure supply, and make cucumbers sustainable and high-yielding.
