The greenhouse cucumber has a strong growth potential, high yield, and requires more fertilizer. At the same time, it does not become a fertilizer for fertilizers. How to do it? Talk about the author's opinion.
Greenhouse cucumber has excellent environment, strong growth potential, high yield and high quality, and has high nutritional requirements. It produces 10,000 kilograms of cucumber fruit per mu and requires 2.5-3.0% of soil organic matter. Available nitrogen, phosphorus, and potassium are 27.3, 13.0, and 34.7 kilograms, respectively. Plus balanced supply of trace elements. The soil organic matter in our county is generally lacking, only 1.24%, ploughing, lack of available nitrogen, and high salt index are the main obstacles that restrict the production of cucumber in greenhouses in our county. Increasing fertility, promoting nutrient balance, and increasing soil production potential in greenhouses are basic measures for high yield and quality of cucumber. How to increase fertility?
The first is to increase organic fertilizer. This is the basis for increasing fertility, and it is also the key to the ripening of newly-built greenhouses. Because organic manure is a complete fertilizer, in the production of greenhouse cucumbers, it can not only supply various nutrients necessary for crop reproduction, but also has a major effect on the continuous high yield of agriculture, the activation of soil nutrients, and the improvement of soil. According to practice, organic fertilizers have the following five characteristics: (1) Organic fertilizers are applied to the soil and are decomposed by microorganisms, which can continuously release various nutrients for absorption by cucumbers, release carbon dioxide, and improve crop carbon nutrition; 2 Organic fertilizers In the process of decomposition, humic acid, humic acid, amino acid, fulvic acid, etc. are produced, which stimulate the seed germination and root growth, and promote the biochemical metabolism of the crop. 3 Organic manure is the main material for soil improvement. During the decomposition process, microorganisms produce secretory enzymes, humus, regulate soil materials and carry out energy transformation, promote the formation of soil aggregate structure, and enhance the ability of soil to retain water and fertilizers; 4 organic fertilizer can improve the efficiency of soil insoluble phosphorus; 5 can increase the yield and Improve quality. Organic fertilizer with appropriate application of quantitative fertilizer, can coordinate the growth of cucumber and the results of contradictions, improve the ability to resist stress, color Guagua straight, full grain, can greatly increase the product rate. General Mushi compost chicken excrement 4-6, with 5-8 square.
The second is to pay attention to the application of biological bacterial fertilizer. Generally, the total soil potassium and total phosphorus per acre are up to 180 and 120 kg respectively, but 80-90% of crops cannot be directly absorbed and utilized. The application of compound growth fertilizer can accelerate the decomposition and transformation of soil organic residues and insoluble phosphorus, potassium and other mineral nutrients. Increasing organic fertilizers and biological bacterial fertilizers and appropriately reducing chemical fertilizers are the inevitable choice for the production of pollution-free green foods. The new greenhouse soil maturation in conjunction with multiple application of biological fertilizer, the practice has proved that: Application of high-quality organic biological fertilizer 7.5 - 10 kg, cucumber plants are robust, sitting more than melon, melon strips long, picking time extension, one application, benefiting the whole growth period The effect is strange.
The third is to extensively apply decomposed human excreta. Nitrogen is the basic element of crop growth and plays an important role in flower bud differentiation and melon strip enrichment. According to the survey, the ratio of nitrogen, phosphorus, and potassium in the soil of greenhouses in our county is 1:1.7:2.4. For many greenhouses with many years of main application of diammonium phosphate, special attention should be paid to supplementing nitrogen fertilizer. Human fecal urine is completely nutrient-rich, and nitrogen is abundant. Each household has its own crop. During the growing period of cucumber, it is widely used to treat human fecal urine. New greenhouses can be poured before planting, but also conducive to raw soil maturity.
