Study On The One-a-day Fertilizers Of Tomato Soil Culture By Drip Irrigation In Greenhouse

One-a-day fertilizers of soil culture by drip irrigation is a new technology that providing the proper water, fertilizers, air for the plant. It has the benefit of not only the soil culture that has the ability of preserving water and fertility but also has the accuracy nutrition management of soiQess culture. Once employed in greenbouse,it will exert better effects man the traditional fertigation in the distribution of providing more balance, steady fertilizers. The traditional fertigation is still providing a large of fertilizers to the plant once a time by drip irrigation. After that, it supply water to the plant and it also use more time to giving water. Because of that, it hinder with plant to absorb the nutrition. In the one-a-day fertilizers culture, water and fertilizer transfer in a limited scope with little evaporation or seepage, which effectively controls the growth of plants, improves the stnicter of greenhouse soil, and preserves its fertility. In other words, the new culture builds a favorable enviroment of water, heat, air and fertilizers for the greenhouse plantThe paper was intended to study the effect about the growth, yield, quality and fertilizes effiency of tomato through processing the experiments of the one-a-day fertilizers soil planting tomato in greenhouse by drip irrigation. We employed the nutrition prescription of horticulture experiments plant of Japan. The experiment have 8 treatments, There have seven X/8 multipe mass-elements nutrition treatments which are 6/8, 5/8, 4/8, 3/8, 2/8, 3/8 no adding microelements,4/8 no adding microelements. The microelements employed the general prescription. The contrast treatment is the traditional using fertilizers to soil by drip irrigation. The result shows: the nutrition treatments growed stronger than the contrast, and more 8.2%~22.8% yield than the contrast, saving 28.2%~74.7% fertilizers weight and saving 61.3%~66.5% fertilizers investment that as 2/8 and 3/8 no adding microelements treatments example, and the quality of nutrition treatments are also better than the contrast treatment The nitrate content in the fruits and soil are lower than the contrast Considering all about that we mink that 2/8 and 3/8 no adding microelement are superior groups. Referring to 3/8 no adding microelements groups we formulate the best manuring table and the best planting technical criterion.
