Problems solved by technology

However, people's requirements for rice quality are increasing day by day, but there are few organic fertilizer sources and high application costs. The large amount of chemical fertilizer input alone has resulted in low soil fertilizer efficiency, soil acidification, insignificant increase in yield, poor rice quality, and bacterial residues. The research and development technology that can be used as organic fertilizer lags behind, especially the application technology for increasing rice yield and improving rice quality is rarely reported

Embodiment 1

[0030] Embodiment 1, the combined application of bacterium residue and nitrogenous fertilizer

[0031] (1) Test material

[0032] The experiment was carried out in the experimental field of Rice Institute of Sichuan Agricultural University. The soil fertility is medium, and the rice varieties are heavy-panicle hybrid indica rice II You 498, which comes from the Rice Research Institute of Sichuan Agricultural University; the japonica hybrid rice Changyou 1 is from the Agricultural Science Institute of Changshu City, Jiangsu Province. Both varieties are mid-to-late maturing varieties, with a wide range of planting areas and regions, and are representative in production. Return the mushroom residues that can no longer be produced to the field directly.

[0033] (2) Test treatment

[0034] A split-plot design was adopted, with varieties as the main plot, and different ratios of bacteria residue and fertilizer in the base fertilizer as the sub-plot. Two treatments were set up f...

Embodiment 2

[0057] Example 2. Supporting water-saving irrigation control and quantitative soil fertility regulation in the main growth period of rice after the fungus residue is returned to the field

[0058] (1) Materials and methods

[0059] It was carried out at the Experimental Farm of Rice Research Institute of Sichuan Agricultural University in Wenjiang, Chengdu (30°70′N, 103°83′E). The soil texture of the plow layer of the experimental field was sandy loam with medium fertility. Two mid-indica late-maturing hybrid rice varieties (both with 17 leaves on the main stem) with basically the same growth period: Dexiang 4103 and Yixiang 3724 were selected as test materials for yield comparison. Dry-raised seedlings, the leaf age is four leaves and one center, the row-to-plant spacing is 33.3cm×16.7cm, transplanting seedlings per plant, and carrying out technical research on water-saving control irrigation and quantitative soil fertility regulation for the main growth period of rice after ...

Abstract

The invention discloses a management method for increasing rice yield and / or rice quality through the use of mushroom dregs. The method includes the steps of using discarded edible mushroom dregs as base fertilizer, applying organic fertilizer as base fertilizer, planting rice seedlings, and performing field management. The discarded edible mushroom dregs are mushroom dregs from waste in mushroom production; special production and processing is not required; the mushroom dregs are applied with organic chemical fertilizer, the technique of returning the discarded mushroom dregs to fields and the technique of field water-fertilizer control are combined, and accordingly the problem that the waste mushroom dregs from mushroom production are difficult to handle is effectively solved; cultivation techniques used with returning the mushroom dregs to fields are integrated, a technical system of fast mushroom dreg conversion and utilization and high yield, high quality, cost saving and efficiency enhancement in rice production is optimized, and a supporting water-fertilizer control scheme is provided. The management method has the advantages that rice yield can be increased, rice quality can be improved, waste is turned into wealth, moisture and fertilizer can be preserved, carbon is low, energy is saved, environment is protected, and the method is of important economic value and application prospect in the sustainable development of agriculture.

Description

technical field [0001] The invention relates to a management method for improving rice yield and / or rice quality by utilizing fungus residue. Background technique [0002] The quantitative index of rice water-saving irrigation has always been an important problem that plagues scientific research and production. Research in recent years has made people more and more aware that the basis for high-yield and high-efficiency irrigation is to clarify the water demand characteristics and water demand indicators in different growth stages of rice. Since the energy point of view of soil moisture research was developed in the 1950s, and after Philip proposed the concept of soil-plant-atmosphere continuum (SPAC) in the 1960s, soil water potential was considered to be the most important and basic requirement for effective irrigation water. sign of soil moisture. In many countries such as the United States, Pakistan, Belgium, etc., it is quite popular to use soil water potential as a s...
