Rational use of naphthalene acetic acid during tomato cultivation helps to increase tomato yield. The following is the use of naphthalene acetic acid shared by the grower Lao Li, let's learn about it!
The grower Lao Li sat on the ground and smoked a cigarette. He said: Looking at you, these people are busy, and they haven't done much. When the tomato harvest is finally finished, the tomato production is still not high. If you don't believe it, you will walk.
He also said: I watched you busy in the field to fight drugs and fertilize all the time. I don't want to say anything, I want to be "prevention first." You are using a hundred pesticides for tomatoes, and they are not as useful as the ones I use.
Neighbors said: I know that you are productive every year, but don't blow it. Let us first tell you what you are doing, or else you will say no more.
I. Soaking seeds before sowing to prevent epidemics
Before planting the tomato seedlings, the planter soaks the seeds with 5~10 mg/kg naphthalene acetic acid solution for 10~12 hours, then rinses them with clean water. After the seed is germinated, the tomato seedlings are neat, robust and cold resistant. It has also been enhanced and can also prevent the occurrence of tomato diseases.
Second, use before and after colonization to prevent viral diseases
In the process of planting tomato, if the seedlings grow fine and the leaves are yellow, after the emergence of the tomato, the grower can spray the naphthalene acetic acid solution 5~7 mg/kg whole plant once, and the tomato seedlings can resume normal growth. .
In the middle and late stages of tomato seedlings, when the temperature in the seedbed is 26 ° C ~ 28 ° C, it is necessary for the growers to spray with 5 ~ 7 mg / kg of naphthalene acetic acid solution, which can prevent the occurrence of tomato early blight. Spray 5 mg/kg of naphthalene acetic acid solution every 10~15 days after tomato planting and slowing down the seedlings, and spray a total of 2 times to prevent the occurrence of early blight and viral diseases.
Third, the use of later, tomato yield increased
Infinite growth of tomato, in the later stage of the results, sprayed with 10 mg / kg of naphthalene acetic acid solution to prevent premature senescence, prolong the harvest period and increase yield. The whole growth period of the tomato (except for soaking seeds) is sprayed with naphthalene acetic acid solution for 5-6 times, which can increase the yield by about 15%.
After listening to the grower Lao Li said this to me, I said: As for your temper, tell the neighbors, others do not necessarily say that you are good. I am planting, I hope everyone has a good harvest.
