Naphthaalene acetic acid is acidic, its main role is to promote growth, promote rooting. Naphthaalene acetic acid is a broad-spectrum plant growth regulator, can promote plant metabolism and photosynthesis.

Agriculture use plant growth stimulant,Guest Posting has endogenous auxin indole acetic role characteristics and physiological functions, such as promoting cell division and expansion, induce the formation of adventitious roots, increased tillering, increased spike rate, increase fruit set, prevent fruit drop, change the rate ratio of male and female flowers. It through leaves, branches and tender skin, seeds and other enter into the plants inside, with the nutrient flow conduit to work.

Paclobutrazol’s agricultural application value lies in its crop growth controlling effect. paclobutrazol has retard plant growth, inhibit stem elongation and shorten the festival, promote plant tillering, increase plant resistance, improve the yield and other effects. paclobutrazol is suitable for rice, wheat, peanuts, fruit, tobacco, rapeseed, soybeans, flowers, lawns, etc. for ( plant ) material, the use effect is significant. The usage and dosage of paclobutrazol in litchi tree: Use 5000mg/L of paclobutrazol wettable powder, spraying the new pumping raw winter shoot, or before the winter shoot germination 20d soil application of paclobutrazol, per plant 4g, inhibit winter shoot growth, reduced leaf area, compact crown, promote heading and flowering, increase the proportion of female flowers.

The usage and dosage naphthalene acetic acid used in litchi trees: in the condition of lychee excessive growth, not germination, using 200-400mg/L of naphthalene acetic acid solution sprayed whole tree, can inhibit the growth of new shoots, increasing the flowers number, improve fruit yield.

Control shoot and flower technology’s principle is based on the requirements of different various flower bud, after harvest, timely drainage tip 2-3 times, in last fall cane turn green or mature can be carried out the control winter shoot, promote bud management measures. Use plant growth regulators can successfully control the germination of lychee winter shoot, promote flowering, increase the proportion of female flower rate, cultivate strong spikes, lay a good material basis for the following year flowering.

Naphthalene acetic acid is a widely used adjusting agent, which at low concentrations can stimulate plant growing, prevent flower drop and so on; while high concentration also can inhibit plant growing. According to farmers reflected, after spraying the naphthalene acetic acid, the pepper leaves will drop, wilt like hydropenia, and used the greater amount, this performance last longer, the harm to pepper will be greater, more likely to cause pepper flower drop. Therefore, while farmers use naphthalene acetic acid should be note the following points:

First of all, well control the drug concentration. Generally, to pepper plants which performance flourishing in began bear fruit, can choose 5% of the naphthalene acetic acid agent, per 15 kg water dissolve 3 to 4 ml, can be sprayed from the upper part of the plant; to more serious flourishing plants can be use naphthalene acetic acid to the barrel 5 to 7 ml. Secondly, spraying according to plant size, growth, to the growing a little fast plants, farmers can spray liquid around 1800 plants every barrel, for the more serious flourishing plants can be sprayed around 1500 plants. Again, pay attention to the weather. If encounter continuous cloudy after spraying, leaf wilting hard to recovery timely, will affect pepper flowering and fruit setting.
