With the continuous expansion of facility cultivation, the annual planting of cucumbers and the huge scale of production have been formed. However, some malformed melons are also often found, such as curved melons, bee-stemmelons, big heads (bellied) melons, pointed head melons, and so on. Lighter ones reduce yields, affect prices, and are severely unable to sell. They have become cultivation facilities. In particular, there are serious problems with the cultivation of facilities in autumn and winter.
As the name suggests, malformed melons are melons that have abnormal growth and development. Deformity is a phenomenon, and the reason is to find it from the process of growth and development. In the process of growth and development, it is directly related to the flower bud differentiation and pollination process. It was observed that the majority of cucumber flower buds differentiated and formed at the seedling stage, beginning with bisexual flowers, and then differentiated into male flowers and female flowers, and only female flowers could be developed into melon strips after pollination. In this process, if certain growing conditions are not met or are affected by something bad, the flowers of the two sexes will cease to differentiate, and often have malformed melons. If the pistil or anthers are not fully developed or pollinated well, abnormal fruit will appear. .
So what are the factors that affect the normal development of cucumber? The first is water and nutrition. On the one hand, cucumbers require loose and fertile soil in the vegetables, sufficient moisture, and high calories, and on the other hand, they are weak in roots, have poor regenerative ability, and are not tolerant of low temperatures and are prone to dampness. Planting cucumbers must ensure adequate and balanced moisture and nutrients. Here, we particularly emphasize equilibrium. Can not be a moment of lack of water, waterlogging, lack of fertilizer, or early post-nutrition over-fertilization, but also pay attention to the balanced application of nitrogen, phosphorus, potassium and trace elements.
Followed by temperature and light. The ground temperature is lower than 13°C, higher than 30°C, the temperature is lower than 8°C, and higher than 40°C will cause the development to stop and form malformed melons. The same is true for light, and it takes 8 to 11 hours of light each day during the cucumber growing season. Illumination, melons, and malformed melons can result from excessively high or low light intensity and light intensity.
In addition, pest damage, vine vines or melon trusses, or some unreasonable cultivation and management measures may lead to malnutrition, developmental arrest, resulting in malformations, such as excessive use of pesticides (especially hormone pesticides), excessive leaf picking or Seedlings, planting density is too large, pruning operations damage and so on.
By clarifying the above reasons, it is not difficult for us to control the deformed melon, but all measures should be completed in advance. Once malformed melons occur, they can only be removed early to reduce losses. Foliar top dressing or spraying with brassinolide has a certain effect, but the main effect is to prevent malformation afterwards.
Plastic additives, also known as plastic additives, are compounds that must be added to polymers (synthetic resins) to improve their processing properties or to improve the properties of the resin itself. For example, in order to reduce the molding temperature of PVC resin, to make the product soft and added plasticizer; Another example is to add foaming agent in order to prepare light weight, anti - vibration, heat insulation, sound insulation foam plastics; The thermal decomposition temperature of some plastics is very close to the molding temperature, and the molding cannot be done without adding heat stabilizer. Therefore, the plastic assistant agent occupies a particularly important position in the plastic forming process. A class of auxiliary agents for plastic molding products, including plasticizer, heat stabilizer, antioxidant, light stabilizer, flame retardant, foaming agent, antistatic agent, mildew agent, colorant and whitening agent (see pigment), filler, coupling agent, lubricant, mold release agent and so on. Colorants, brighteners and fillers are not special plastics chemicals, but the general use of materials.
