Our common view is that the high yield of crops requires large roots, deep roots and roots. This type of root system is the basic feature of drought-resistant crops. In actual production, any method of promoting root growth is regarded as a measure for drought-resistance and yield-increasing measures. If we study the root system of different crops with a root analyzer, it is found that the root system of the drought-tolerant crop is indeed more developed than its root system, which also contributes to its drought resistance. Absorbing more moisture provides the foundation.
The intensive root system will consume a large amount of can be used for canopy assimilation products, and the crop root system and the canopy have a dependence-dependent and coordinated balance relationship. A certain amount of photosynthetic products are used for the root system, and the distribution to the crown will inevitably be reduced. Water utilization The rate also decreases. Many crops account for about 10% of total dry matter weight at harvest, which is at least underestimated by losses due to dark breath, old root loss, microbial decomposition, animal phagocytosis, root exudation and sampling, and pretreatment. %.
Passi's research shows that the consumption of assimilation product and water and fertilizer are at least twice the weight of the production unit. Extensive derooting experiments showed that removal of part of the root system had no effect on canopy growth, and the crop could grow beyond the extra roots required for its growth. The behavior of the root system did not necessarily correspond to the behavioral structure, and the biomass and yield of the canopy were also non-linearly related. A large canopy may not necessarily be supported by a large root system. In order to cope with the conditions of soil drought and avoid the crops from being subjected to water stress, it is essential to fully consider the cost and cost of constructing the root system while promoting roots, which cannot be lost. To solve whether high-yield crops always have or do require larger root systems, the key to determining the types of crops that require more root systems and more economics in different environmental conditions and growth stages is to select the measurement criteria and determine the ultimate goals, while focusing on the establishment of Comprehensively evaluate general-purpose quantitative tools that are effective for such complex dynamic relationships.
Dioctyl Adipate is one of the most extensively used plasticizers in plastics/rubber processing. It has comprehensive properties, such as high plasticizing efficiency, low volatility, UV-resisting property, water-extracting proof, cold-resisting property, and also of good softness and electric property.
Chemical properties:
A colorless, transparent, oily liquid with a slight odor. Do not dissolve in water, soluble in organic solvents such as ethanol, ether, acetone, acetic ACID.
Usage:
Used as an excellent cold-resistant Plasticizer for polyvinyl chloride, which can impart excellent low-temperature softness to products.
1.Insoluble in water, soluble in methanol, ethanol, ethyl ether, acetone, acetic acid, chloroform, ethyl acetate, petrol, toluene, mineral oil, vegetable oil and other organic solvents, slightly soluble in ethylene glycol.
2.As cold plasticizer, it can be usedc in polyvinyl chloride, polyethylene copolymer , polystyrene, cellulose nitrate, ethyl cellulose and synthetic rubber as an typical cold plasticizer,with high efficiency, small heat discoloration; it can give product a good softness at low temperature and light fastness
