Increased and Less Rice Production before Fertilization
How to achieve high efficiency and low consumption in rice production, so that farmers can really increase grain and income? Wu Yuemin, a senior agronomist at the Provincial Agricultural Technology Extension Station, put forward a good proposal: Farmers must fertilize rice to “appropriately increase the middle and early period and reduce the amount of later applicationâ€. According to Wu Yuemin, the number of fertilization is more and more labor is used to increase the production cost, and the fertility is not ideal. Because during the growth of rice, 80% of the nutrient nitrogen absorbed before July comes from topdressing, and the nitrogen fertilizer needed in the later growth period comes from the soil. Therefore, the late application of nitrogen fertilizer can not be immediately absorbed by rice, both affecting growth and causing waste. In addition, the protein content of rice is about 8% on average. If the application of granular fertilizer is large, the protein content of rice will increase by one-third, while for rice quality, the higher the protein content, the worse the taste. In view of the widespread rice farmers' practice of “multi-fertilization can make more foodâ€, Wu Yuemin said that from the previous comprehensive calculations, there are many nitrogen fertilizers, although the output has increased, but it does not increase income. He reminded the farmers: “The use of 5 kg of potassium fertilizer, 10 kg of diammonium, and 30 kg of urea on an acre of rice land is common practice, and diammonium is best applied once during transplanting.â€
