Various
. species, varieties have different sensitivities to plant growth regulators,
. which should be the bases to pick various plant development regulator and usage
. concentration. For example: Apricot was not delicate on paclobutrazol, the
. dosage needs to be increased. Development regulators work in plant growth and development,
. make certain to use in the appropriate time, too early or far too late can not attain the
. preferred effect. For example: naphthalene acetic acid utilized in young fruit duration
. was playing the thinning impact, while used before choosing fruit can avoid
. preharvest fruit dropping. Applications need to remain in the appropriate duration,
. making sure to use the time, normally better to use prior to 10:00 in warm windless day, the drizzling
.
According . to the plant reactions decide the utilized number, usually one time, however if the . outcome is bad, it is required to repeat using, really conscious the response . can be utilized sometimes with a small amount. For instance: with daminozide . control apple saplings thriving and flower is needed to use 2-3 times once . every 10 days. The dosages need to be managed, such as liquid spray as damp for . the degree. Make a range of representatives used in combination. Often the . production need to resolve a number of issues at the same time, can be utilized in . conjunction. To those can not react each others drugs can be combined, to play the . benefits and avoid weaknesses. For instance: in order to early the pear supply . duration, while usage the ethylene ripening, in order to avoid dropping, can be . mixed with the naphthalene acetic acid. However, some agents, such as . daminozide must not be mixed with other alkaline agents, or will impact the .
results.
Numerous
. plant development regulators themselves are not extremely steady, such as indole acetic
. see light decay, ethychlozate loose effect when fulfill alkali and acids,
. naphthylacetate have volatility, must be effectively saved according to their physical
. and chemical homes, or will reduce the efficacy. Note that numerous
. farming technologies match each other. Growth regulators are just
. worked in one part of plant development and development, not an alternative to
. fertilizers, pesticides and other agricultural steps, to make agricultural
. production application get the desired results, make certain to fulfill other
. farming technical measures. For example: with naphthalene acetic acid, IAA treated cuttings to promote rooting, it needs to keep certain
. humidity and temperature level within the seedbed, otherwise rooting is challenging
. ensured. In brief, the application of development regulators should be
.” positive and prudent”, take numerous elements into account
