Growth regulator, a class of pesticides used to regulate plant growth and development, includes synthetic compounds and natural plant hormones extracted from organisms. Net farming finishing the six major roles of plant growth regulators, the following detailed enumeration, for users reference.
What's the effect of plant growth regulators on crops?
A break, plant seed dormancy, germination by:
seed and storage such as freshly harvested seeds, immature seed, maturity and harvest when the environmental conditions are not good or bad storage too long low germination rate or germination, seedling emergence and slow or weak, thus affecting the germination rate, increase the amount of. The seeds such as gibberellin can break dormancy, promote germination, increase germination rate of seeds, and make seedlings early and strong.
What's the effect of plant growth regulators on crops?
Two, to promote root crops to increase tillering, short seedling cultivation:
as growth retardant helps to overcome the adverse environmental conditions, the formation of short delay seedling growth, seedling. Paclobutrazol, chlormequat has better effect of seedling cultivation, the main application methods are seed treatment and seedling spraying.
What's the effect of plant growth regulators on crops?
Three, promote plant full grain filling:
such as production, often through the use of auxin, gibberellin and cytokinin plant growth regulators to promote grain filling of rice and wheat. Such as rice and wheat in booting, flowering and filling stage with a fine spray fertilizer cytokinin, yield Ling and other growth regulators, the transfer rate in different extent enhanced the intensity of photosynthesis and nutrient to the reproductive organs, prolong the functional period of leaves, accelerate the filling speed, increase grain weight, yield increase.
What's the effect of plant growth regulators on crops?
Four, control of plant growth and prevent lodging:
such as wheat and other cereal crops tend to lodge in later stages, especially those of high stalk varieties. In high water and fertilizer area, even short stalked varieties still have the possibility of lodging. The application of growth retardants can effectively control growth, reduction of high anti collapse, increase production.
What's the effect of plant growth regulators on crops?
Five, to prevent the plant flower and fruit drop, in order to promote strong:
such as cotton, beans, melons and other crops in addition to indefinite inflorescence flower and fruit drop is related to environmental conditions and cultivation techniques, and vegetative growth and reproductive growth status and hormone balance. In the production, auxin and growth retardant can be used to improve their growth status and hormone balance in vivo, so as to prevent the fall of flowers and fruits, and improve the fruit setting rate.
What's the effect of plant growth regulators on crops?
Six, promote the maturity of plants:
such as endogenous hormones, fine fertilizer division, has the role of anti-aging; ethylene and abscisic acid can accelerate aging and promote maturity.
