AI Technical Summary

Problems solved by technology

[0004] The above manual adjustment methods have high technical requirements for personnel, are difficult to master, time-consuming and laborious, and have the characteristics of delay, so they can only play a remedial role; while the above chemical adjustment methods have a single idea, and they are all directly selected to adjust the growth of the above-ground parts. There is a problem of production reduction due to excessive suppression of plant height

Embodiment 1

[0032] 1. Test object Rice, variety Gangyou 158

[0033] 2. The test agent 90% calcium regulating cyclamate original drug and 80% chitooligosaccharide original drug were provided by Sichuan Guoguang Agrochemical Co., Ltd.

[0034] 3. Medication period One week before rice jointing.

[0035] 4. Test method Quantitatively weigh out the calcium and oligochitosan required for the test, prepare the required concentration according to Table 1, and set the clean water treatment as a blank control. After preparing the liquid medicine, spray it at the jointing stage of rice, and the dosage is 80ml / m 2 , Each processing 1m 2 , Repeat 4 times.

[0036] 5. Statistical analysis of the data After the rice is sprayed, 9 samples are selected diagonally, and the plant height of the rice at 65 days after the treatment (when the rice is mature) is measured, and the plant height inhibition rate is calculated. The calculation formula is as follows

[0037] Node height inhibition rate = (control plant heigh...

Abstract

The invention discloses a plant growth adjusting composition, and a preparation and an application thereof. The composition comprises prohexadione calcium and chitosan oligosaccharide according to a weight ratio of 1:(0.02-1). The composition or the preparation shortens the height of crop internodes, reduces the plant height, effectively inhibits nutrients and growth of overground parts, promotes root growth, and improves the absorption ability on nutrient substances in the soil in order to improve the lodging resistance and increase the yield.

Description

Technical field [0001] The invention relates to the field of plant growth regulators, in particular to a plant growth regulator composition, preparation and application thereof. Background technique [0002] In the practice of rice production, lodging often occurs, especially under the action of strong wind and heavy rain, it is more likely to cause the stalk to fall, and generally reduce the yield by 10-30%. At the same time, it brings inconvenience to harvesting and threshing, increases the loss rate of rice, and limits the increase in yield. [0003] The lodging of rice is related to plant height, internode length, stalk material, panicle type, root system, and cultivation conditions. There are two methods of artificial regulation and chemical regulation. The first is to cultivate dwarf or lodging-resistant varieties. Breeders start from cultivating dwarf varieties and cultivate dwarf varieties to basically solve the problem of rice lodging; second, reasonable cultivation measu...
