Reasons for the occurrence of malformed fruits in summer vegetables

There are four main reasons for the occurrence of malformed fruit in summer vegetables, which are malformation caused by poor flower bud differentiation, malformed fruit caused by poor nutrient supply, malformed fruit caused by viral disease and malformation caused by hormone poisoning.

Malformation caused by poor flower bud differentiation: Generally, the flower bud differentiation occurs in the seedling stage. When the tomato grows to 2 leaves and 1 heart, the internal flower bud differentiation has already begun. When the colonization is 7-9 pieces of true leaves, the life is Flower bud differentiation has ended. If abnormal environmental changes occur during this period of time, it is easy to appear deformed. In this regard, to solve the malformation caused by flower bud differentiation, we must first cultivate strong seedlings, and prevent the occurrence of high temperature, drought and other conditions for a long time in order to avoid affecting flower bud differentiation and lead to deformity.

Abnormal fruit caused by abnormal nutrient supply. Abnormal fruits such as hollow fruit, small fruit, and stiff fruit are mostly caused by the uncoordinated growth of vegetative growth and reproductive growth. It may also be caused by too many fruit setting to make the nutrients synthesized by the leaves unable to meet the growth of the fruit. Excessive application of nitrogen fertilizer, excessive growth of above-ground nutrient, and imbalance of root-crown is one of the main causes of hollow fruit; soil drought, excessive application of phosphate fertilizer, etc. can easily cause calcium deficiency in plants, which can easily cause umbilical cord fruit of tomatoes. In this regard, comprehensive fertilizer and water supply and plant control measures should be adopted.

The malformed fruit caused by viral disease is the most harmful one. The virus is divided into several types, such as mosaic virus and streak virus. These viruses force the grown fruit to turn into fruit, green fruit and tumor. Face bumps, loss of commodity value. In this regard, it is necessary to prevent viral diseases in advance, and specific measures have been mentioned in this article.

Hormone poisoning is also an important cause of tomato malformation. The currently applied hormones include 2,4-D, anti-fallin, gibberellin, etc. Improper use can cause empty fruit. When using hormones, adjust the concentration continuously according to changes in the environment. The concentration of ginseng hormones mainly changes depending on the temperature. The temperature is high, the concentration of hormones is low, and the temperature is low.

Wedge Prism

Wedge prism is an optical element having plane-inclined surfaces, usually the faces are inclined toward one another at very small angles. Wedges divert light toward their thicker portions.

Wedge prism is commonly used in laser system for eliminating the reflections from the second surface or for beam steering.circle wedge,square wedge,irregular wedge...Every materials,sizes,wedges and coatings may be available by custom orders. Standard and broadband antireflection coatings are available upon request.
