Embodiment 1

[0026] From May 2007 to May 2008, the research results of the effect of amaranth-oil tanker cropping on the yield and quality of rape on the gray brown purple mud soil.

[0027] The implementation method is as mentioned above: fine soil preparation→sowing and raising seedlings→transplanting→fertilization→management→observation and recording of growth status in each growth period→harvesting→sample determination→data collation→result analysis. Among them, the test fertilizer for grain amaranth: farmyard manure, compound organic fertilizer; the test fertilizer for rapeseed: superphosphate, compound organic fertilizer.

[0028] 1. In May 2007, on gray-brown purple mud soil, after measuring its basic chemical properties, three grain amaranth crops, Red Amaranthus K112, Red Amaranth R104, and Lvsui Amaranth No. The sweet potato planted for feed was used as the control.

[0029] 2. After the grain amaranth was harvested in mid-September 2007, hybrid rapeseed was planted, and the same ...

Embodiment 2

[0034] From May 2008 to May 2009, amaranthus-rape crop rotation was implemented on the purple soil, and the method steps were the same as in Example 1.

[0035] 1. In May 2008, on the purple soil, after measuring its basic chemical properties, three kinds of amaranths with red amaranth K112, red amaranth R104 and Lvsui amaranth No. 3 that passed the national approval and promotion were used as the predecessors, and they were used for planting and feeding Sweet potato was used as a control.

[0036] 2. After the seed amaranth was harvested in September 2008, Brassica napus was used as the subsequent plant, and rape was planted in the soil that had not been planted with the seed amaranth (planted with fodder sweet potato) as a control. The rapeseed was matured and harvested at the end of April 2009. The result is as follows:

[0037] 1. The organic matter, total nitrogen, total phosphorus, total potassium, available nitrogen, available phosphorus, and available potassium of the...

Embodiment 3

[0041] From May 2009 to May 2010, amaranth-oil tanker cropping was implemented on the newly reclaimed slope farmland in the Three Gorges reservoir area, and the method steps were the same as in Example 1.

[0042] 1. In May 2009, after measuring the basic chemical properties of the soil, three grain amaranths, Red Amaranthus K112, Red Amaranth R104, and Lvsui Amaranth No. 3, which had passed national approval and promotion, were used as the predecessors, and sweet potatoes for feeding were planted For control.

[0043] 2. After the grain amaranth was harvested in September 2009, Brassica napus was used as the subsequent plant, and rape was planted in the soil where forage sweet potatoes had been planted as the control. The rape was matured and harvested at the end of April 2010. The result is as follows:

[0044] 1. The soil nutrients after planting amaranth in the newly reclaimed slope farmland are organic matter 20.84g / kg, total nitrogen 3.22g / kg, total phosphorus 1.12g / kg,...

Abstract

The invention discloses a crop rotation method capable of quickly improving agricultural soil productivity in the Three Gorges reservoir area. Grain amaranth with obvious soil fertility is used as the preceding crop and the k-favoring crops and rape as the succeeding crops; then, azotobacter, phosphate-solubilizing bacteria and potassium-releasing bacteria which are separated and obtained from the grain amaranth root soil are prepared into mixed fungicide of which the national standard bacteria content is 10*108 / ml; the mixed fungicide is applied to the succeeding crops to organically combine rotation crop with fertility of dry land, so that the improvement of N, P, K and B nutrient in agricultural soil is taken as the breach to accelerate the growth of the succeeding crops and improve the quality and the quantity. The invention can solve the problems of poor agricultural soil productivity in the Three Gorges reservoir area, even Chongqing and the whole country, shortage of green feeds, reduction of rape planting area, gap of colza oil in markets and the like.

Description

technical field [0001] The invention relates to the technical field of crop planting, in particular to a crop rotation method for rapidly improving agricultural soil fertility in the Three Gorges reservoir area. Background technique [0002] Crop rotation is an important part of the crop planting system, one of the important technologies of modern "circular agriculture", and also the traditional experience of my country's agricultural intensive cultivation and coordinated use and cultivation of soil. The promotion and application of crop rotation technology has many functions and benefits such as making full use of natural resources, increasing soil biodiversity, improving soil physical and chemical properties, promoting crop growth and development, continuously increasing crop yield, effectively improving product quality, reducing costs, and increasing income. , is considered to be a "costless production increase technology", and has been widely adopted by countries all ove...
