Abstract

The invention is applicable to the field of rice planting and provides an accurate fertilization method for high-yield field rice. The method comprises the following steps: selecting a land parcel with better fertility and applying 30-50 kg per mu of a soil conditioner and a base fertilizer according to a proportion of (5-7):10; after rice seedlings are sown, supplementing 5 kg / mu of a seedling fertilizer; after the rice seedlings are sown, applying 13 kg / mu of urea; after the rice seedlings are sown, applying 13-15 kg / mu of a base fertilizer; applying 50-75 kg / mu of a soil conditioner and a base fertilizer according to a ratio of (5-7):10; after a rice field is pretreated, applying 20-30 kg of a base fertilizer and 18-25 kg of a silicon fertilizer to each mu before the rice seedlings are transplanted to the rice field; after the rice seedlings are inserted into the rice field, conducting fertilization for the first time when the rice seedlings turn green and grow, and applying 9-12 kg of a base fertilizer, 7-8 kg of urea, 8-10 kg of a microbial organic fertilizer and 2-5 kg of a zinc fertilizer per mu; and after the rice field is sun-dried, applying 12-18 kg of a base fertilizer and 9-12 kg of urea per mu before watering. The method effectively improves the rice yield and remarkably reduces disease symptoms.

Description

technical field [0001] The invention belongs to the field of rice planting, in particular to a method for precise fertilization of rice in high-yield fields. Background technique [0002] Rice is the most constrained crop by water and soil resources. There is not much room for growth of rice arable land in my country. However, with the continuous increase of the total population, my country's demand for rice is bound to increase. Affected by factors such as increased rice planting labor costs and production cost investment, the contradiction between increasing grain and increasing income in rice planting has become increasingly prominent. Therefore, the high-yielding fertilization strategy of rice under the dual objectives of increasing yield and increasing efficiency has strong practical value and practical significance. [0003] Fertilizers are made from minerals, water and air through chemical and mechanical processing. Most of the chemical fertilizers are inorganic fer...
