Irrigation fertilizer special for sauropus androgynus

Abstract

The invention relates to an irrigation fertilizer special for sauropus androgynous. The irrigation fertilizer is prepared by mixing urea, potassium dihydrogen phosphate, potassium sulfate and strong base to obtain a mixture and adding water for diluting. The irrigation fertilizer is designed according to the physiological characteristics of a sauropus androgynous plant and has high specificity; a buffer solution balance system is introduced, so that a diluted fertilizer solution can always keep in a weakly alkaline state, the content of cadmium in a sauropus androgynous planting land is controlled, the adjustment of acid soil is facilitated, the absorptive amount of cadmium ions by a crop root system is lowered, and the product quality of the sauropus androgynous is enhanced; and the irrigation fertilizer has the characteristics of simple production process, high fertilizer utilization ratio, uniform application, quick plant absorption, high efficiency, remarkable yield increasing effect and the like.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and relates to a plant nutrient fertilizer, in particular to a kind of fertilization specially used for arborina. Background technique [0002] Sauropus androgynus (Sauropus androgynus) scientific name is Shougongmu, also known as Wuzhishan Wild Vegetable, Tianluxiang, etc. It belongs to Euphorbiaceae and is a small perennial shrub. It is native to the tropical regions of Southeast Asia. It is wild and cultivated in Hainan, Guangdong, Guangxi, Fujian, Yunnan and other places in my country. The young shoots are picked for vegetable food. Shuzai has high nutritional value, rich in protein, vitamins and minerals, among which the protein and vitamin C are more than 20 times that of ordinary vegetables, and the content of carotene and vitamin B2 is more than 10 times that of ordinary vegetables. In addition, After being fried (or boiled), the saber vegetable has a delicate and crisp taste, delici...

AI Technical Summary

Problems solved by technology

At present, the fertilization method for the production of saplings is still the traditional fertilization method, that is, applying sufficient base fertilizer before planting, and topdressing solid chemical fertilizers regularly during the growth of saplings. This method has several deficiencies: 1. The traditional fertilization method is not based on the physiological Formulated fertilization according to the proportional characteristics of nutritional requirements, the blindness of fertilization is large, the utilization rate of fertilizer efficiency is low, and the waste is serious

Although the traditional fertilization method can meet the production requirements, there are many kinds of fertilizer products on the market, and the quality varies. Long-term application is difficult to control the pollution of cadmium in the fertilizer to the soil of the planting site, which affects the quality of the saber vegetable product.

3. Studies have shown that the PH value of the soil can affect the absorption of cadmium in the sapling vegetable. In order to control and reduce the cadmium content in the sapling vegetable, it is required to keep the soil PH value neutral or weakly alkaline. However, due to the various fertilizers available in the market The PH value is not uniform, and most of them are acidic. Long-term application cannot control and adjust the PH value of the soil, and it is difficult to ensure product quality.

4. Fertilization with traditional fertilizers (such as granular compound fertilizers) is not uniform enough, and the fertilization method is backward, labor-intensive and time-consuming

[0005] In the face of stricter quality control requirements for the production of saplings, the existing traditional fertilizers and fertilization methods cannot meet the requirements for the production of high-yield and high-quality saplings. Therefore, it is of practical significance to develop special fertilization for saplings that is suitable for the production of high-yield and high-quality saplings.
