crop roots are the source of power for crop growth. if the roots are not good, the growth of crops will be problematic. the resistance to adversity is poor and the crops are vulnerable to diseases and insect pests. therefore, in agricultural operations, the protection of plant roots is a necessary work, so how to carry out the maintenance of crop roots?
first of all, we should do a good job in soil management, that is, to create a good living environment for the root system. when planting crops, we should ensure that the soil is not too wet or too dry. these two conditions will lead to poor soil permeability, which is not conducive to the growth of roots. it is suggested that farmers should water properly according to soil moisture, and drip irrigation is better for some greenhouse vegetables. the medium tillage and loosening of soil during the period is beneficial to the growth of root system.
soil nutrient supplement should be done well. soil fertility decreases year by year along with crop cultivation. it is suggested that middle and trace element fertilizers containing nitrogen, phosphorus and potassium should be sprayed in the soil together with organic fertilizers as base fertilizer, so as to increase the content of humus in the soil and create a good environment for root growth.
for some fields where chemical fertilizers are used perennially, soil hardening is easy to occur. it is suggested that farmers should pay attention to the combination of bacterial fertilizers when using fertilizers. the beneficial bacteria in bacterial fertilizers can improve soil quality and improve the utilization rate of nutrients in soil. for some greenhouse vegetables, it is suggested to spray some bacillus subtilis and so on. bacillus subtilis is one of the most common beneficial bacteria used in agriculture in recent years. species.
good soil management, but also need to promote the growth of the root system itself! when using fertilizers, it is suggested to use some fertilizers containing humic acid and alginic acid. humic acid and alginic acid have obvious rooting effect. for vegetable areas, it is suggested to use some liquid fertilizers containing alginic acid and humic acid directly, with faster effect and better effect.
for some crops whose roots are susceptible to disease, such as beans, farmers are advised to do a good job in disease control. there are two ways to prevent and cure diseases. one is to recommend that farmers mix seeds and use clotrile, spermatophore and chlorpyrifos. these medicines have good preventive effect on root diseases. it is also suggested to add brassinolide when mixing seeds. this regulator has obvious effect on promoting rooting. or after planting crops, spray some medicines to prevent and cure root diseases.
finally, foliar spraying also has a certain promotion effect on root growth. it is recommended that farmers spray potassium dihydrogen phosphate, silicon fertilizer, aminophyll ester and so on. phosphorus and potassium fertilizer can promote root growth and improve stress resistance. silicon fertilizer can make root more tough, promote cell division, and aminophyll ester can also promote rooting.
if the crop wants to grow well, the root system is very important, and the root system is developed, then it absorbs more nutrients, can adequately supply the growth of the crop, make it grow well and have strong resistance to stress. therefore, peasant households must pay attention to the maintenance of root system in management.
