Description
Technical Field
The invention relates to preparation and application of a water culture nutrient solution, in particular to application of the water culture nutrient solution in pepper cultivation.
Background
As an important component of modern agriculture, facility agriculture is rapidly developing with incomparable advantages of traditional agriculture, and becomes an effective means for farmers to increase income and income in many regions. With the rapid development of facility agriculture year by year, the problems caused by continuous cropping of facility soil secondary salinization, soil-borne diseases and the like are serious year by year, the yield and the quality of vegetables are reduced, the production environment is polluted, the soil available for agriculture is reduced year by year, and the sustainable development of the facility agriculture is restricted; the water and fertilizer is the key for improving the yield and quality of vegetables, but the problems of inconsistent yield, quality and water and fertilizer utilization efficiency of greenhouse vegetables are severe. The soilless culture technology is an effective way for solving various problems, can effectively avoid the problems of soil salinization, soil-borne diseases and the like caused by long-term continuous cropping of the traditional soil culture, can improve the utilization rate of crops on water and nutrients, is a novel high-tech agricultural technology for producing safe, high-quality and high-yield agricultural products, and is a novel way for developing green and high-efficiency agriculture. Soilless culture has many advantages and is more and more paid attention by people. The soilless culture replaces the soil environment with the artificially created crop root system environment, so that the problem of contradiction of water, air and nutrient supply which is difficult to solve in the traditional culture can be effectively solved, the crop root system is in the most suitable environmental condition, and the maximum production potential is exerted; the soilless culture is combined with intelligent management, so that the industrial production and the automatic operation are realized, and the labor and the force are saved; the soilless culture enables the crop production to get rid of the restriction of soil, and greatly expands the available space of agricultural production; the soilless culture integrates multiple disciplines and multiple technologies, and is beneficial to realizing the modernization of agricultural production.
The inorganic substrate cultivation is one of the soilless cultivation modes, which means that rock wool, vermiculite, sand, perlite and the like are used as fixed supporting materials for crop growth, and water, fertilizer, oxygen and environment required by the growth are provided for crops by nutrient solution. Due to the stable physicochemical property of the matrix, the contained mineral components can not interfere the nutrient solution, and can not provide nutrient components which can be absorbed and utilized by plants, thereby being easier to realize the accurate control of the soilless culture water fertilizer. The inorganic matrix does not contain nutrient components, so that nutrients required by the growth of crops completely depend on the supply of nutrient solution, and the supply according to needs and the accurate regulation and control of the nutrient supply of the crops can be realized. By adopting the inorganic matrix for cultivation and utilizing the nutrient solution circulation high-efficiency utilization technology, the utilization rate of the water and fertilizer can be improved, the water and land pollution caused by the outflow of the traditional water and fertilizer is avoided, and the method has important significance for water-saving, fertilizer-saving and environment-friendly cultivation production. The preparation of the nutrient solution is not only the core technology for the normal growth of the inorganic substrate cultivated vegetables, but also the foundation and the key of the soilless culture. The success of substrate cultivation depends on the parameters of nutrient solution formula, concentration, proportion of various nutrient elements, pH value, solution temperature and the like to a great extent, and whether the nutrient solution management in the plant growth process can meet the requirements of different growth stages. The quick, high-yield and high-quality cultivation result can be obtained only by adopting a correct nutrient solution formula and preparing and managing the nutrient solution according to a proper method so that the plant is in the most suitable nutrient solution environment at any growth and development period. The composition and concentration of the nutrient solution are different according to the types, growth periods, environmental conditions, cultivation purposes and the like of crops. The composition of the nutrient solution directly influences the absorption and growth conditions of crops on nutrients, and is related to the problem of economic and effective utilization of the nutrients in the fertilizer, and the formula composition and the concentration regulation in use of the nutrient solution are important links of soilless culture. In the process of cultivating vegetables by using the inorganic matrix, the application of the nutrient solution in cultivation is influenced by the types of crops, the growth period, the temperature, the illumination and other conditions.
The pepper is an annual or perennial herb of berries capable of forming peppery or sweet taste in the capsicum of the solanaceae family, is native in central and south america, is one of main varieties of horticultural crops cultivated by facilities, is various, comprises big lamp cage pepper mainly comprising sweet pepper, long pepper mainly comprising ox horn pepper, sheep horn pepper, linear pepper and screw pepper, clustered pepper mainly comprising eagle pepper and the like, is rich in nutritional value, is more and more popular with the masses, and the cultivation area of the pepper is gradually enlarged in recent years. The cold countries or regions mainly cultivate sweet peppers, and the tropical and subtropical countries or regions mainly cultivate peppers. Plant nutrition research shows that different crops have different requirements on various nutrient elements and the proportion thereof, and even if the same crop has different growth and development periods, the proportion and the concentration of the various nutrient elements are also different (the reference document: guo Shirong master edition, soilless culture, chinese agriculture publishing company, first edition 1 month 2003, P117.) the concentration (EC value) of the hot pepper nutrient solution in different growth stages is different, and the scientific and reasonable nutrient solution is prepared, so that the balanced growth of plants can be promoted, and the utilization efficiency of the fertilizer can be improved. Most of the currently used nutrient solutions are Japanese garden test and Kawasaki nutrient solution formulas, and the nutrient solutions are difficult to adapt to the diversity requirements of different areas, different vegetable varieties and different cultivation seasons. And in the process of nutrient solution cultivation, a complete set of production technology system does not exist in nutrient solution preparation, supply mode, liquid supply frequency, liquid supply amount and EC values in different periods. The optimum nutrient solution formula and the matched scientific and reasonable irrigation frequency and irrigation quantity can effectively regulate the proportion of gas, water and fertilizer in the matrix, promote the growth and development of plants and improve the fruit quality.
