Embodiment 1

[0025] Spray tap water on the rice leaf surface by 18Kg / mu at the bracting stage, the initial ear stage and the full ear stage.

[0026] The paddy rice planted by the method described in this embodiment has a seed setting rate of 71.00%.

Embodiment 2

[0028] Spray 60 g / mu of a foliar fertilizer for improving the seed setting rate of hybrid rice disclosed in Example 9 of CN102503659A on the rice leaf surface at the budding stage, the initial heading stage and the full heading stage.

[0029] That is, the production of a foliar fertilizer that improves the seed setting rate of hybrid rice: (1) 200 grams of gibberellin (GA4), 600 grams of mepizom and alcohol were mixed and dissolved for 2 hours, and 100 grams of organic silicon surfactant was added L-77, add 1250 grams of talcum powder and stir for 10 minutes; the product is dried and pulverized at 25°C;

[0030] (2) Mix 300 grams of amine fresh fat, 2100 grams of water-soluble silicon fertilizer, 900 grams of chelated zinc, 900 grams of copper chloride, and 300 grams of sodium dodecylbenzenesulfonate with the above mixture, stir well, and then add 3350 grams of filler, after stirring evenly, the wettable foliar fertilizer powder product is obtained.

[0031] The paddy rice p...

Embodiment 3

[0045] An application of active ingredient Lepidimoide extracted from tender okra fruit, comprising the following steps:

[0046] 1) Preparation of LM extract, the active ingredient extracted from tender okra fruit: Clean the fresh okra fruit picked within 24 hours, sterilize the surface, put it directly into a dry fruit press and squeeze it, remove the okra pods and squeeze them, and pour them into Add 1.25 times the weight of pure water to the squeezed juice, and stir evenly, then let it stand for 2.0 hours, filter through a 100-mesh filter, remove the filter residue, and the filtrate is the active ingredient LM extract of okra tender fruit, and put it in Store in -20°C refrigerator for later use;

[0047] 2) After diluting the active ingredient LM extract of okra tender fruit prepared in step 1) by 800 times, dilute the active ingredient LM extract of okra tender fruit at the budding stage, initial ear stage and full ear stage by 15Kg / mu sprayed on rice leaves:.

Abstract

The invention discloses application of an active ingredient Lepidimoide extracted from tender okra fruits. The application comprises the following steps: (1) preparing extracting solution of active ingredient LM of tender okra fruits; and (2) diluting the extracting solution of the active ingredient LM of tender okra fruits prepared in the step (1) by a certain multiple, spraying diluent of the extracting solution of the active ingredient LM of tender okra fruits in the earing period, initial heading period and full heading period on rice foliage. According to the method, the extracting solution of the active ingredient LM of the tender okra fruits is sprayed to the rice in the earing period, initial heading period and full heading period, so that the setting rate of organic rice is improved; because the okra is an edible food, and pods of the okra do not contain any synthetic hormone or chemical preparation, the production requirements of the organic rice are met; compared with the traditional organic rice planting method, the application of the active ingredient lepidimoide extracted from tender okra fruits disclosed by the invention is low in treatment cost, and the setting rate is relatively improved by 8.19%; the method is easy to operate and convenient for large-scale application; and moreover, the new application field of the okra is widened, and the economic value is improved.

Description

technical field [0001] The invention relates to the application of an active ingredient Lepidimoide extracted from tender okra fruits, in particular to a method for improving the seed setting rate of organic rice by applying the active ingredient Lepidimoide extracted from tender okra fruits. Background technique [0002] Okra, also known as okra clip, coffee ambrette, commonly known as croissant and eggplant, is an annual herb of Malvaceae. The tender fruit of okra contains a lot of mucus. The main component of this rare viscous substance contains a large amount of a An oligosaccharide bioactive substance Lepidimoide, referred to as LM. [0003] LM is a new type of plant growth regulator similar to natural hormones, which can promote plant flowering, plant seedling growth, increase plant seed production, etc. Yamada et al. used ultraviolet spectrophotometry to detect the chlorophyll content in the cotyledon samples of plants treated with LM and dark treatment, and proved t...
