Description
Technical Field
The invention relates to a vegetable planting technology, in particular to a special transpiration resistant agent for vegetables and a using method thereof.
Background
The agricultural production of China gradually changes from pursuit of yield to improvement of quality, and the mode of high yield is replaced by the mode of large investment of water and nutrients in the traditional planting, so that the waste of water and fertilizer resources is caused, the morbidity of crops is improved, the quality is greatly reduced, and the problems of environmental pollution and the like are caused. Deficit irrigation provides a drought adverse environment to improve fruit quality by properly controlling irrigation water, and becomes a research hotspot in recent years.
However, water content in plants is reduced due to deficit irrigation, leaves and plants are wilted by severe plants, and normal photosynthesis and CO are affected2The method is characterized in that the method comprises the following steps of assimilating, yield loss, reducing water loss in crops to the greatest extent, reducing adverse effects of water stress, improving quality due to deficit irrigation, and achieving the highest yield, wherein currently, drought-resistant chemical regulating and controlling substances are used for reducing plant transpiration rate, reducing water loss and controlling transpiration, so that the method becomes an important research direction for water-saving agriculture development, and multiple chemical drought-resistant substances capable of promoting crop root system water absorption and reducing transpiration strength are researched, wherein the poplar flood is divided into four categories according to chemical composition and biological activity, namely ① phytohormone or plant growth regulator, ② inorganic compound, ③ micromolecule organic matter and ④ organic macromolecule.
At present, the most applied agents mainly comprise an antitranspirant and a plant growth regulator, wherein the antitranspirant mainly comprises three types of metabolic type, film forming type and reflection type, the metabolic antitranspirant mainly influences the drought resistance of crops by influencing the activity of an enzyme activity system in a plant body, fulvic acid is the most widely applied metabolic antitranspirant, the drought resistance is improved by improving the osmotic potential of cell membranes, and good drought resistance and income increasing effects are achieved on the crops such as wheat, corn, potatoes, fruit trees and the like. The film-forming type transpiration inhibitor reduces transpiration, reduces water loss, delays crop wilting and improves drought resistance by forming a film on the surface of the leaves. The method is mainly applied to landscape nursery stocks and flower transplanting, inhibits the plants from rapidly losing water, improves the survival rate, and is suitable for short-time or accidental drought. The brassinolide compound is a sixth plant hormone which is internationally recognized as efficient, broad-spectrum and nontoxic, is an important regulating substance of plant reaction to stress, is called as 'stress relaxation hormone', improves the drought resistance of crops by inducing drought response genes, and can improve the content of drought-resistant substances in leaves by spraying on tomato seedlings. However, the anti-transpirant for the facility vegetables is developed less, and particularly, a special product for the middle and later growth periods is lack of irrigation, so that the quality can be ensured, the loss of yield is reduced, and the economic benefit is maximized. Reflective anti-transpirants reduce leaf transpiration by reflecting solar radiation energy, but are less practical because they do not selectively absorb and reflect solar radiation.
