Problems solved by technology

[0005] The purpose of the present invention is to provide a kind of fertilizer based on oil-rice-rice three-cropping system and a light and simplified planting method, which solves the problem of insufficient soil fertilizer in the "oil-rice-rice" three-cropping system, tight stubble time, and high labor intensity. Low production efficiency and other issues, this planting method effectively uses straw nutrients to fertilize the soil, and realizes light, simple, high-yield, and efficient cultivation

Embodiment 1

[0029] A method for fertilizing and lightly simplifying planting based on oil-rice-rice three-cropping system, the steps are:

[0030] The first step, Daejeon selection

[0031] In the oil-rice-rice three-cropping area, randomly select a field that is being planted with late rice and is convenient for drainage and irrigation.

[0032] The second step, no-tillage transplanting of rapeseed, mulching and returning to the field with late rice straw

[0033] 1) About one month before the harvest of late rice, select fields with medium fertility, loose soil, flat terrain, close to water sources, and convenient irrigation and drainage as seedbeds. The area ratio of the seedling field to the field is 1:6, so that the seeds are evenly sown, and the varieties with tall plants, many branches, many siliques, and moderate maturity are selected, such as double-low rapeseed Huashuang 5 and Zhongshuang 10. Hybrid rapeseed Zhonghua Youza No. 12, Huayouza No. 14, Wanyou No. 22, Qinyou No. 7, ...

Embodiment 2

[0061] From 2013 to 2015, in Zhougan Village, Dajin Town, Wuxue City, Hubei Province, the experiment of fertilization and light and simplified planting of oil-rice-rice three-cropping system was carried out. Huayouza 12 was used for rapeseed, and Ezao 18 was used for early rice. The late rice is selected from Fengyuanyou 299, and according to the basic steps of Example 1, the specific test method in this example is as follows:

[0062] Rapeseed was no-tillage and transplanted during the season (the spacing between plants and rows was 25×30cm), and base fertilizer was applied to holes. Nitrogen (N), phosphorus (P) during the whole growth period 2 o 5 ), potassium (K 2 0) the consumption of fertilizer and borax is respectively 14kg / mu, 5kg / mu, 10kg / mu and 1kg / mu; 60% of nitrogenous fertilizer, potassium fertilizer is as base manure, 20% is as overwintering fertilizer, and 20% is as moss fertilizer; Phosphate fertilizer, boron fertilizer One-time application as basal ferti...

Abstract

The invention discloses a fertilizing and simplified planting method based on a rape-rice-rice triple cropping system. The method includes the steps that 1, after late rice is harvested, rape is transplanted without tillage, late rice straw is returned to the positions between the lines of the transplanted rape in a covering mode, and base fertilizer is applied in a hole application method; 2, rape straw is cut into broken segments or smashed to be returned to the field, overturning, base fertilizer applying and uniform raking are carried out, and early rice seedlings are lifted and transplanted on the same day; 3, when the late rice is planted, overturning, base fertilizer applying and uniform raking are carried out, late rice seedlings are lifted and transplanted on the same day, early rice straw covers the positions between the lines to be returned to the field, and the straw needs to be trampled to be soaked in water. It is achieved that rape-rice-rice triple cropping system crop straw is completely returned to the field, straw nutrients are effectively utilized, and soil is fertilized; transplanting without tillage is achieved in the rape season, the double-cropping rice is transplanted after overturning is completed, power consumption is reduced to a certain degree, and the problem that crop growth periods are severely affected by short crop rotation time of the triple cropping system is effectively solved.

Description

technical field [0001] The invention belongs to the technical field of soil fertilization and light and simplified cultivation, and in particular relates to a method for fertilizing and light and simplified planting based on oil-rice-rice three-cropping system. Background technique [0002] Oil-rice-rice refers to the continuous planting of three crops of rapeseed, early rice and late rice in the same field. The southern double-cropping rice and three-cropping area is located in the subtropical and tropical humid monsoon climate. It governs Hunan, Jiangxi, Guangdong, Guangxi, Qiong, Fujian, Zhejiang, Hubei, Anhui and other provinces and municipalities. Commodity grain and oil base. With the rapid advancement of industrialization and urbanization, a large number of rural laborers, especially young and middle-aged laborers, have transferred to non-agricultural industries. The abandonment of large areas of paddy fields or the change from multi-cropping to single-cropping resu...
