Irrigation method for inducing downward growth of root system based on wet point duration deviation

Abstract

According to the irrigation method for inducing the downward growth of the root system based on the wet point duration deviation, the draft of the root system in several days is judged based on the wet point duration deviation, then soil water, fertilizer and gas vertical regulation judgment is conducted, the water and fertilizer liquid is made to be located at the position far away from the root tip all the time, and the root system can grow downwards according to the water and fertilizer tropism principle and the stress effect of the root system. Inducing the root system to gradually grow downwards. Therefore, root systems among plants are prevented from winding to grab nutrients during close planting, the contact area of the root systems and soil is increased, and the root systems fully absorb moisture in deep soil, so that waterlogging resistance, drought resistance and wind resistance of crops are improved, and stable yield and yield increase of the crops are facilitated. After induction is finished, the drip irrigation device can be used for subsequent irrigation requirements, layered fixed-point fixed-area drip irrigation with controllable flow can be carried out on crop roots, nutrient requirements of different root areas can be met, and efficient water saving is achieved.

Description

technical field [0001] The invention relates to the technical field of agricultural irrigation, in particular to an irrigation method for inducing downward growth of roots based on wet point duration deviation. Background technique [0002] The deeper the root system of crops goes underground, the more breathing and absorbing roots are distributed around, the more nutrients in the soil are absorbed, the more vigorous the nutrient cycle, and the stronger the branches, leaves and trees. In the traditional irrigation technology, there is unevenness in water and fertilizer irrigation. During the growth process of the root system, the lateral roots are mostly distributed horizontally in the shallow soil layer. Due to the unevenness of irrigation, the roots often gather in one place, and when the crops are densely planted, it is easy to snatch neighboring plants. This is not conducive to the absorption of nutrients by the root system, making the nutrient absorption efficiency not ...

Problems solved by technology

[0004] The purpose of the present invention is to provide a kind of irrigation method based on the wet point time length deviation to induce the root system to grow downward. During the root growth period, the root system can be induced to grow downward as much as possible, so as to reduce the root system entanglement between plants and solve the problem of snatching neighboring plants when field crops are densely planted.
