AI Technical Summary

Technical Problem

Xianghe glutinous black rice variety "Gou Nengdang" has strong regionality and generally low yield, which leads to poor growth and development under conventional planting conditions and poor resistance, which hinders its scale, intensiveness and factoryization. Development of planting.

Method used

Provide a nutrient solution containing phenylalanine and salicylic acid, with a final concentration of 0.2mM phenylalanine and 20μM salicylic acid, for the improvement of the plant biomass, plant height and Chlorophyll content is suitable for rice seedling cultivation from the third leaf to fifth leaf stage.

Benefits of technology

Effectively promote the planting effect of "Gou Nengdang", improve the plant's biomass, plant height and nitrogen content, enhance its adaptability, achieve a small increase in yield, and solve the problem of malignant growth and regional restrictions. The problem has promoted its factory-based seedling cultivation and large-scale promotion.

Abstract

The invention relates to the technical field of rice planting methods, in particular to a nutrient solution for cultivating fragrant rice glutinous rice Matrimony Festival and application and a cultivation method of the nutrient solution. The invention provides a nutrient solution formula and a culture method suitable for growth and development of Matrimony Antheraea Brassica, aiming at Matrimony Antheraea Brassica, a common rice nutrient solution added with exogenous amino acid and exogenous organic acid can be used, and a common rice nutrient solution subjected to compound treatment by adding phenylalanine with the final concentration of 0.2 mM and salicylic acid with the final concentration of 20 [mu] M is added, so that the yield of Matrimony Antheraea Brassica is increased. The plant height, the biomass (fresh weight), the nitrogen content, the chlorophyll content and the dry weight of a single plant of the Meiban can be effectively improved, and the method is an optimal treatment mode. According to the method, the technical problem that an effective culture method is lacked in the prior art can be solved, and large-scale, intensive and factory planting management and large-area popularization and application of dominant rice varieties in the Guizhou region are better promoted by utilizing synergistic interaction and advantage complementation among different treatment modes.
