What is the matter of buying the same variety of tomatoes grown at the same time as the neighbor, and when it is almost ripe, the neighbor's tomato is very large, and the tomato grown by the family is very small?
The above phenomenon is very common in rural vegetable gardens, and most of the reasons for this situation are caused by the fact that tomatoes are not effectively managed in time after entering the puffing period, or management errors.
In response to this situation, in this article, the little helper will tell you in detail that after tomatoes enter the puffing period, the 4 management that need to be done can effectively promote the expansion of tomato fruits and make tomatoes bear large and many.
- The first management: do a good job of water and fertilizer supplementation
After tomatoes enter the puffing period, the consumption of water and nutrients is relatively large, so if you want to promote the expansion of the fruit, the supply of water and nutrients cannot be interrupted. Especially in summer, the field is relatively arid, pay attention to irrigation and watering, replenish water.
In terms of nutrients, some friends just spread some compound fertilizer in the field before planting tomatoes, and then no longer top dressing. Tomatoes consume a lot of nutrients before entering the puffing period. After entering the puffing period, more nutrients are needed, but the nutrients in the soil are insufficient, and if top dressing is not carried out at this time, it is easy to cause the tomato fruit to be smaller due to insufficient nutrients.
Especially in relatively barren plots, such as some farmers in front of their own wasteland, feel that it is a waste not to plant something, just simply sort out the planting of tomatoes, this kind of plot is generally not highly fertile, if top dressing can not keep up, tomato results are very small, or even not fruitful.
There are 2 ways of top dressing, one is ground top dressing and the other is foliar spray fertilization. Ground top dressing is mainly compound fertilizer, and compound fertilizer with high nitrogen and high potassium is recommended. Here is a reminder, do not apply chlorine-containing compound fertilizer, mainly potassium sulfate type. At the same time, you can also add some superphosphate, if there is farm fertilizer is better.
The foliar spray fertilization, mainly supplementing some trace elements, such as boron, calcium, magnesium, zinc, iron, etc., can promote the growth of tomatoes, but also improve flower bud differentiation, prevent split fruit and so on.
- The second management: do a good job of suppressing prosperity
Tomato in the planting process, the appearance of vigorous growth is very common, if not controlled, tomatoes continue to grow upward, will continue to consume more water and nutrients, and when the tomato enters the fruit stage, due to the insufficient water and nutrients absorbed, the fruit will become smaller.
After the control of prosperity, the tomato no longer grows upward, and the water and nutrients transmitted by the root system are greatly reduced, and the fruit development is supplied instead, which promotes the tomato to grow larger and larger.
There are generally two types of measures to control the population. First, the "heading" treatment is carried out, that is, the head of the tomato is artificially cut off to prevent it from growing upwards, so as to promote the supply of nutrients to the fruit growth.
Second, spray the control agent, can use paclobutrazole or enbutrazole for control, pay attention to the dosage when spraying, do not "control death" at one time, it is recommended to spray a small number of times, about a week can see the effect of controlling wang, the stem is thick and strong, promote the increase of the fruit.
- The third management: properly do a good job in fruit thinning
After tomatoes enter the fruiting period, the more fruits on a plant, the better, not greedy for more. Especially the first ear fruit, if the number is too large, it will affect the number and size of the second ear fruit and subsequent ear fruits.
The more tomato fruits in the first ear, the more water and nutrients need to be consumed, and the greater the impact on subsequent fruits. Some farmers think that the more fruits they have, the higher the yield, and they can't bear to thin the fruit, which eventually leads to a small number and size of the whole tomato plant.
It is recommended that the first ear of fruits be kept 3-4, not too much, if 5-6 fruits are produced, 2-3 need to be manually picked. For each subsequent ear, it is also recommended to keep about 4-5 fruits, not too much.
- The fourth management: do a good job of spraying plant growth regulators
Some plant growth regulators can promote cell division, which in turn causes fruit to expand, and many farmers are also called "bulking agents". Regarding its use, some farmers believe that it should be banned, which may make tomatoes unsafe to eat. Some farmers consider it normal that plant growth regulators are common in agricultural production.
Spraying plant growth regulators, to a certain extent, can indeed play the role of puffing fruit and promote the enlargement of tomatoes. For example, the p-chlorophenoxyacetic acid used on tomatoes can not only puff the fruit, but also prevent the fall of flowers and fruits, so that the tomatoes bear large and many.
The above four managements, after the tomato enters the puffing period, have a positive effect on promoting the growth of tomato fruit. If you want tomato fruits to be large and numerous, management is indispensable. It not only affects the quality of tomatoes, but also affects the yield of tomatoes, hoping to attract the attention of growers.
