The method of an easy contact, applied is described at cultivation of plants. Results of researches of scientists of the English agricultural college led on plants with use of a new method are given. The method interferes with a pulling and thinning of hothouse plants.
It is interesting to know
You noticed, how often skilled gardeners and agriculturists, passing by the plants, as if accidentally carry out on their leaves a hand – as if want to stroke. It appears, they do it because touches help plants to become stronger. More often plants (on sprouts) grow up in sparing conditions, in the closed heated rooms, from it they are extended, become thinner and weak, than in habitat.
To stop pulling process (especially in the winter), "commercial" plant growers are compelled to use chemical regulators of growth. But to define norms of their introduction happens hardly, and secondary processing often is required.
Researches which are carried out by graduates of English agricultural college of Hedlou in Kent County, Great Britain, aimed to develop special equipment of control over height of sprouts and shanks. The method of a touch is thus used, which is directed on causing in plants a mechanical stress.
Scientific researches showed that plants most actively react to a touch early in the morning. Thus their different types react differently: to some plants of rather short cycle, longer stress that their growth stopped is necessary for another or was considerably slowed down.
Assume that one of the main hormones which is liberated at an easy contact – is gas ethylene. At artificial processing of plants by it reaches the same effect that at the contacts method.
Besides, ethylene is applied to many other purposes at different stages of development of a plant, for example, for stimulation of maturing of fruits, by flowerings or dormant period extensions.
Method application an easy contact can be effective where grow up plants and sprouts of vegetables. However to use it in big hothouses it is quite difficult because of various height of plants.
But it is not necessary to subject plants to too strong stress. The superfluous physical irritation very much influences hormonal balance that conducts to the sharp termination of growth. Therefore it is not recommended to carry out more than 20 cycles "contacts" in day. One cycle – is two movements back – forward. It is possible to use a piece of a piece of cardboard or plastic, and it is possible to carry out a hand.
It is obvious that biochemical consequences of a method of an easy contact are extremely various, but one is clear: if you want, that your plants turned out not extended, sickly and pale, and had strong short stalks – more often them iron!
