Embodiment 1
[0030] 1. Preparation of growth regulators
[0031] (1) Weigh a certain amount of pure lanolin (99% purity), stir on a magnetic stirrer and heat to 40°C to melt.
[0032] (2) According to different formula ratios, weigh the corresponding amount of medicine to be added, dissolve in absolute ethanol, stir evenly, pour into lanolin, stir on a magnetic stirrer at high speed, so that the medicine is evenly distributed in lanolin.
[0033] (3) Due to the volatilization of ethanol, the weight of the mixture decreases. After 3-5 hours, weigh the mixture in step (2), and stop heating when the weight reaches the sum of the mass of lanolin and the added agent (that is, the ethanol volatilization is complete). Stir and dispense the medicine.
[0034] There are ten treatments in the experiment. Treatments No. 1 to No. 8 are self-prepared. The medium is lanolin. Each treatment contains the following drugs:

Abstract
The invention belongs to the technical field of fruit tree production, and relates to a plant growth regulator and a preparation method as well as application thereof. The plant growth regulator comprises lanolin as a matrix and 2.5-3 percent of GA(3+4+7), 2-5 percent of calcium nitride, 2.2-2.8 percent of boric acid, 1-5 percent of potassium nitride and 290-310 ppm of CCPU serving as ointment. The growth regulator is convenient to manufacture, the use method is simple, the nutrients required for development of fruits is fully guaranteed, the efficacy is lasting, the single fruit weight of pears is obviously improved, the weight is increased by 36.6 percent, the inherent quality of the fruits is not reduced, and the appearance quality is improved to a certain extent. Compared with the common plant growth regulators on the market, the plant growth regulator has the advantages that the single fruit weight of the pears is obviously increased, the content of mineral elements of the fruits is increased, and the problems of shorter effective action time and short shelf life of the pears after treatment of other plant growth regulators are solved.
Description
technical field [0001] The invention belongs to the technical field of fruit tree production, and relates to a plant growth regulator and its preparation method and application. Background technique [0002] Pear fruit has high nutritional value, crisp and juicy, strong flavor, rich in sugar, acid, minerals, vitamins, etc., and is deeply loved by consumers. However, due to the short fruit development period of some varieties, and the influence of adverse factors such as rainy season and insufficient sunshine, there are often problems such as small fruit weight, low per unit yield, low uniformity, poor appearance quality, and low commerciality. For example, the golden pear, which is widely planted in many areas of our country, generally has oblate fruit, with yellow-green skin when ripe, and turns golden yellow after a little storage. Soft and juicy, white flesh, very few stone cells, high edible rate, sweet and fragrant, unique flavor, excellent quality, but in recent years...
