Novel amino acid fertilizer and application thereof in chrysanthemum planting

Abstract

The invention relates to a novel amino acid fertilizer and application of the novel amino acid fertilizer in chrysanthemum planting, in particular to a planting method of a cutting chrysanthemum. The method comprises a first step of fertilizing base fertilizer, a second step of planting and a third step of fertilizing additional fertilizer, wherein the additional fertilizer fertilized in the additional fertilizer fertilizing step is amino acid fertilizer or alternative non-amino acid type additional fertilizer. In some preferred modes, the method maintains the water content of a planting matrix to range form 15% to 40%. The method can facilitate the increase of cut-flower plant dry weight; the absorption of nitrogen, phosphate and potassium in plants is promoted, and the nitrogen, phosphate and potassium content in soil is reduced remarkably; meanwhile, the appearance quality and refreshment quality of cut-flowers can be improved, and the vase lifetime after the flowers are picked is prolonged by 2-5 days.

Description

technical field [0001] The invention relates to the field of plant planting, in particular to a novel amino acid fertilizer and its application in chrysanthemum planting. Background technique [0002] Cut flower chrysanthemum (Chrysanthemum morifolium Ramat) is an important commodity in the world's flower trade. Cut flowers occupy a large share in my country's cut flower production. Statistical Data Analysis of Flowers. Chinese Flower Horticulture, 2011(13): 18-21). Compared with general crop products, cut chrysanthemum is a high value-added product, and its cultivation is basically specialized all over the world. [0003] In the cultivation of cut chrysanthemums, improving its yield and quality are the two most important basic goals. In order to increase the yield, shortening the planting cycle is a very important means, especially under the conditions that can be planted every year in southern my country. However, like other crops, the planting of cut chrysanthemums also...

AI Technical Summary

Problems solved by technology

However, the existing technology has not yet solved the problems caused by the lack of rotation in the professional planting of cut chrysanthemums through fertilization management, such as unreasonable water and fertilizer application, low fertilizer utilization rate, deterioration of soil environment, and decline in the quality of cut chrysanthemums. The planting cycle of cut chrysanthemums is more flexible to meet the market's requirements for the timing of the cut chrysanthemums, and the problems of poor appearance and freshness of cut chrysanthemums have not been solved through fertilization management

[0006] In the prior art, in the planting process of cut chrysanthemum, there are unreasonable application of inorganic chemical fertilizers, low fertilizer utilization rate, and degradation of soil environment quality [KaplanM, TokmakS, et al.Salinization problem in Antalya region greenhouse soils and recommendations[J].International Symposium on Techniques to Control Salination for Horticultural Productivity, 2000, 573,: 401-406; Druege U, Zerche S, Kadner R, et al.Relation between nitrogen status, carbohydrate distribution and subsequent rooting of chrysanthemum cuttings as affected by pre-harvest nitrogen supply and cold-storage[J]. Annals of Botany, 2000, 85(5): 687-701.], professional planting of cut chrysanthemum planting [Nosengo N.Fertilized to death[J].Nature, 2003, 425(6961): 894-895] and other problems, so it is necessary to explore the above-mentioned problems in the planting of cut chrysanthemums by fertilization management. Improving the quality of cut chrysanthemums, promoting the sustainable development of the cut chrysanthemum industry, saving energy and increasing environmental and economic benefits have extremely important practical significance
