Recently, the situation of excessive victimization in controlling prosperity is mainly caused by Xiaomiao's "puffiness" and not being resistant to drugs. The emergence of small seedlings "puffiness" is mainly caused by the high temperature and low light environment in the early stage and the poor management of vegetable farmers: on the one hand, the high temperature and low light environment causes serious growth of tomato seedlings, which is not conducive to the accumulation of organic nutrients and the transportation to the root system; On the one hand, excessive watering further aggravated the length of the seedlings, and at the same time caused poor soil air permeability, which was not conducive to rooting. "Puffiness" of seedlings is mainly manifested as: thin stems, long joints, weak growth and flat heads after the plants grow to a certain extent; the roots are small and the root system is weak, and the root layer is shallow. This kind of "puffy" seedlings is very different from our conventional leggy growth. Their growth potential and sustained growth ability are relatively weak. Therefore, the management of this kind of seedlings should "maintain roots." "Combination of maintenance and control", the following measures are taken in management: Control watering, and control the frequency and amount of watering after the seedlings are slowed down properly. When the surface sees dry, use hoeing to promote root piercing and cultivate a strong root system. Reasonable application of rooting agent. At this time, the rooting agent should be mainly used to increase the amount of root coefficient and extend the root length. High-phosphorus rooting agents such as phosphomagnesin and other rooting agents such as alginic acid and chitin can be used. Bacteria flushing to improve the soil. Inverted seedlings to control prosperity For the elongated seedlings, do not hang the seedlings first, put the seedlings down to weaken the vertical growth of the plants and cultivate strong seedlings. Medicament control proliferation at this time is mainly for plants without "flat head", and it is not recommended to control proliferation of "flat head" plants. When spraying, you can choose Guoguang Chlormequat 0.5~1 bottle/barrel, potassium dihydrogen phosphate 50g/barrel, and control prosperity should be light.
