The summer tomatoes kind of difficult, but in previous years have never seen such a severe deformity fruit, what causes deformity fruit more, should be how to deal with?
The problem in front of the flower more
Nearly period of time, seeds, fruit, etc happen more, farmers are very concerned about.In fact, the problem such as seeds, fruit, have identified before flowering, is just also look not to come out before flowering.Analysis the reason, mainly is the early stage of the flower bud differentiation, such as the dew seed fruit bud differentiation is incomplete.
Tomato flower bud differentiation from 1-2 true leaf had already started, to believe in four leaf one heart engraftment, second it have begun to development.If after seedling period and engraftment of abnormal high temperature and low temperature, the problem such as water shortage, deficiency, the adr, especially the duration is long, can easily affect the flower bud differentiation, increases the risk of deformity deformity fruit and flowers appear.
PengShi observed deformity fruit more, usually plant growth is not normal, excessive or too weak will affect the function of root system.Many times we require farmers before flowering fruit cultivating good strong root system, its purpose is help to form a strong tree, more important is to ensure that the absorption of root system and good capability.
The root is the main organ of absorption of mineral nutrition, the root absorbing ability strong and the weak also determines the level of the ability of nutrient supply.Before flowering fruit, strong root system can meet the needs of the plant vegetative growth and reproductive growth of mineral elements, and once the root system of absorptive capacity gradually weak, nutrition supply problems, then it will affect the growth of aboveground part, will immediately to cause serious influence the reproductive growth of plants.
Heat the suitable sowing conditions
Before and after the summer crop of tomatoes engraftment, temperature, dry climate, good lighting, relatively speaking is favorable for seedling growth, should make full use of light temperature conditions, foster healthy plants.
If the barn temperature is too high, you can override sun-shade net or spraying cooling agent, reduce films transmittance, reduce relative temperature.It is important to note that the shade in the summer is not excessive, otherwise easy to form a relative high temperature and weak light environment, plant thin, is likely to exacerbate deformity fruit, fruit difficult problems.In rain weather, pay attention to the vents rain pass, stop the rain, ensure PengShi inside and outside the well ventilated, avoid rain after relative high temperature "stuffy tent".
Pick a heart removable nipple
If the deformity fruit, fruit more difficult problems, such as, simply by increasing concentration of hormone side effects is very big, but not necessarily better.
Advised farmers take heart removable nipple method, picked in tomato fruit after 2-3 ears, removal of plant growth, keep a growing more prosperous collateral.Lateral branch growth and development of late, if early bud differentiation is affected, pick a removable nipple is a better solution.Pick heart, of course, removable nipple before checking their plants in detail to determine the main cause of deformity fruit, eliminate hidden dangers and after spraying the alginate, boron fertilizer and so on to regulate in advance to pick the heart again, otherwise the problem still exists, pick heart long after the lateral branch bud differentiation is still bad, also lost the significance.
