Cucumber blooms in the open?

Cucumbers cultivated in open field in summer sometimes have no luster and produce a layer of white powdery cream on the outside. This phenomenon is commonly known as "frosting fruit." Cucumber blooming is a physiological disease that causes cucumbers to lose their proper color, greatly reduces the commercial quality of cucumbers, and affects the income of farmers. After years of practice and exploration, the author summarized the causes and prevention measures of cucumber blooming in open areas. The following are introduced:

First, the cause

The cultivated land is too shallow, the roots are shallow, the absorption is not strong, or the cultivated land is large, the soil layer is too thin, and the nutrient supply is insufficient; the cucumbers are aged at the late stage of growth and the root absorption capacity is reduced; the pests and diseases are serious, the plants are aging, and continuous cropping Plots are malnourished; temperatures, night temperatures are too high; continuous cloudy days, lack of sunshine, etc. Because of the above factors, the nutrient production of the plant is reduced, and the respiration is enhanced, resulting in insufficient depletion of the respiratory tract and suppressed, and a waxy substance is produced on the peel.

Second, preventive measures

1. N, P and K are applied in combination. The cultivated land avoids too much sand, and fertilizer should also be taken care of at the later stage of growth. Nitrogen, phosphorus, and potassium should be used in conjunction with fertilization, and reasonable rotation should be observed.

2. Deeply turn the earth. The cultivated land should be deep-turned more than 30 cm. If there is no deep-turning condition, the mu can be used to spray the ground with 200 grams of water before planting, and 100 kg of water can be applied to the ground before the planting, or when watering, do not plunge into the ground with water. After about 20 days, about 50 cm. Deep soil can be fluffy and transparent. This can promote root growth and absorption.

3. Pay attention to pest control. In the later stage of growth, pests and diseases must also be prevented to prevent plant premature aging.

4. Pay attention to spraying foliar fertilizer. Every 7 to 10 days spray 1 love to take more solution, enhance the photosynthesis of leaves, produce more nutrients, to avoid respiration inhibition.

5. Reasonably choose rootstock. When using black-skinned squash as rootstock, cucumbers tend to bloom. When using imported Japanese pumpkin as rootstock, the cucumber produces little or no frost.

Laser Distance Meter

Laser distance measure is a very convenient tool for various types of applications in industries, construction and house decoration. Laser distance meter is a very useful device which gives accurate measurement of distance, area and volume especially in large areas such as rooms, apartments, buildings, real estates, factories, warehouses, infrastructures, gardens, roads, and many other applications requiring accurate results for distance , area and volume measurement.

Trade your heavy tape measure for laser rangefinder, which let you simply take measurements with one hand. No matter your job, the laser rangefinder will help you measure much farther, with greater accuracy and in more situations, saving you money and time.
