Problems solved by technology

At present, the relatively mature rice high-yielding technologies in my country mainly include the three-yellow and three-black theory, soil testing formula fertilization, precise quantitative fertilization, leaf age pattern fertilization, nitrogen fertilizer back-shift fertilization, and balanced fertilization, etc., but the overall fertilization principle for high-yield cultivation is saturated fertilization. Often due to the influence of external conditions, it leads to excessive application of fertilizers in practical applications, waste of resources, and pollution of the environment
High-yield rice planting often suffers from yield reduction due to excessive fertilization, and aggravated pests and diseases

Embodiment 1

[0029] In Nanfeng Village, Zhongtai Street, Yuhang District, Hangzhou City, demonstration planting of Yongyou 12, a super-wide-adapted super rice variety, was carried out using soil testing and compound formula fertilization, with an yield of 850 kg per mu, a fertilizer rate of 35%, and a blank control yield of 300 kg per mu (converted into Mu alkaline hydrolyzable nitrogen = 169.23 kilograms), the fertilization category and quantity are as follows in Table 1:

[0030] Table 1: Super Rice Fertilizer Operation Planning

[0031]

[0032] The slow-release special fertilizer for the soil test formula mentioned in the above table uses the special compound fertilizer for rice approved by the Zhejiang Provincial Department of Agriculture, N:P 2 o 5 :K 2 O=20:8:12, effective content ≥ 40%, produced by Hangzhou Lishi Chemical Fertilizer Co., Ltd. The organic fermented fertilizer uses rich soil enzyme fertilizer, N ≥ 5%, and 3 billion beneficial bacteria per gram, produced by Shan...

Abstract

The invention discloses a fertilizer saving and insecticide reducing method for super rice in low-temperature rainy climate. The method includes the following steps of optimizing the yield structure, wherein an eurytopic super rice variety high in ratio of grain to straw is selected, the yield target and the yield structure of relative stable production are determined according to a moderate source, a smooth flow and a large warehouse, and indexes of all construction yields are made; optimizing the planting flow path, wherein by means of the soil testing and fertilization technology, the method of combining slow-release fertilizer, quick-acting fertilizer and fermentation fertilizer is used for composite formula fertilization, and soluble silicon fertilizer is applied additionally in the whole flow path; optimizing the fertilization mode, wherein the optimal fertilization effect is achieved according to the TRIZ theory, and composite formula fertilizer is applied as basic tillering fertilizer for three growth phases of rice. According to the growth and development rule of high-yield cultivation of super rice after the elongation stage on the low-temperature rainy climate condition, technical schemes are optimized and integrated, an external environment coordinates with an internal cause source and course bank of rice, the yield advantage of the super rice variety is brought into play, and disadvantages are avoided.

Description

technical field [0001] The invention relates to the field of formula fertilization of crops and the technical field of super rice cultivation, in particular to a method for saving fertilizer and reducing medicines of super rice in low temperature and rainy climate. Background technique [0002] In 1996, the Ministry of Agriculture formulated the project "Research on China's Super Rice Breeding and Cultivation System". Since then, China has officially and systematically carried out research on super rice. Since 2000, the yield per mu of one-season super rice has broken through 700 kg, 800 kg, 900 kg and 1000 kg successively. [0003] From 2005 to 2014, there were 126 super rice varieties recognized by the Ministry of Agriculture. These super rice varieties are very popular because of their great performance potential, good quality and strong disease resistance. There are also some super rice varieties, but due to their poor adaptability, the promotion area does not meet the...
