Problems solved by technology

In production, there are methods of burning straw and vines, or removing straw and vines from the paddy field, and then re-irrigating the plow and harrowing field. This treatment method is not conducive to the accumulation of soil organic matter, but also causes air pollution, which is labor-intensive and time-consuming. , delayed farming time

Embodiment 1

[0051] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0052] A potato-late rice double no-tillage planting method, specifically comprising the following steps:

[0053] (1) Potato no-till cultivation:

[0054] ①Selection of fine varieties

[0055] Choose mid-maturing, high-yield, strong resistance to stress, and no disease-free varieties of virus-free varieties Faureita and Zhongshu No. 4.

[0056] ② Ditching and plotting

[0057] Drain the field water before the late rice is harvested to keep the field soil moist without water accumulation on the field surface. When the late rice is harvested, it should be harvested as close to the ground as possible, and the rice pile should be kept shallow. Immediately after harvesting, no-tillage furrowing and ditching can be carried out, and ditching ma...

Embodiment 2

[0090] Planting density test of potato straw mulched no-tillage cultivation:

[0091] The experiment was carried out in 2016 in the winter leisure rice field of Fengchuan Town, Fengxin County, Yichun City, Jiangxi Province, and the tested variety was Feiwu Ruita. The test set 5 planting densities, respectively: (1) 75,000 plants / hm 2 ; (2) 82,500 plants / hm 2 ; (3) 90,000 plants / hm 2 ; (4) 97,500 plants / hm 2 ; (5) 105,000 plants / hm 2 . Each density is 1 treatment, each treatment repeats 3, and the area of ​​the plot is 25m 2 , random block arrangement. The soil fertility of the test is uniform, the soil layer is deep, and the drainage and irrigation are convenient. It was used as late rice, and the soil fertility is medium. When the late rice is harvested, it should be harvested as close to the ground as possible, with shallow rice piles, and no-tillage division and furrowing should be carried out immediately after harvesting. The furrow width is 1.5m, the ditch width i...

Embodiment 3

[0096] Experiment on no-tillage throwing planting density of late rice

[0097] The test was carried out in Tianbao Township, Yifeng County, Yichun City, Jiangxi Province in 2015, and the tested variety was II You 527. The test set 5 planting densities, respectively: (1) 170,000 holes / hm 2 ; (2) 220,000 points / hm 2 ; (3) 270,000 points / hm 2 ; (4) 320,000 points / hm 2 ; (5) 370,000 points / hm 2 . Each density is 1 treatment, each treatment repeats 3, and the area of ​​the plot is 30m 2 , random block arrangement. The sowing date was June 5, 2015, and the harvest date was October 10, 2015. The amount of fertilizer applied per hectare is nitrogen (N) 180-210kg, P 2 o 5 90~105kg, K 2 O180~240kg. The results are shown in Table 3.

[0098] The test results in Table 3 show that the yield of late rice varies greatly under different no-tillage planting densities, and the planting density is 320,000 holes / hm 2 The rice yield was the highest at 8486.67kg / hm 2 . Secondly, the...

Abstract

The invention discloses a potato and late rice double-no-tillage cast transplanting planting method, belonging to the field of agricultural production. The method mainly comprises the following stepsof (1) potato no-tillage cultivation including (a) fine breed selection, (b) ditching and raking, (c) potato seed processing, (d) reasonable close planting and the application of enough base fertilizer, (e) covering with straws, (f) field management, and (g) timely harvest, and (2) late rice no-tillage cast transplanting including (a) breed selection, (b) seedling cast transplanting, (c) field management including scientific fertilization, reasonable irrigation, timely weeding and the prevention and control of pests and diseases, and (d) timely harvest. The method provided by the invention hasan obvious influence on the economy, yield and economic benefit of rice, the yield of late rice can be obviously increased, and the method has the characteristics of reducing labor intensity, savingcost and increasing efficiency, increasing production and income, and being simple and easy.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and in particular relates to a potato-late rice dual no-tillage and throwing planting method in the middle and lower reaches of the Yangtze River, which saves time and labor and improves economic benefits. Background technique [0002] The main driving force for the development of agricultural production is to improve production efficiency and increase farmers' enthusiasm for growing grain. Potato-super rice double no-tillage throwing planting refers to the no-tillage planting of potatoes in the winter slack field after the harvest of late rice. A planting mode of throwing late rice. At present, the number of migrant workers in rural areas is increasing, and agricultural production is increasingly developing in the direction of lightness and simplification. Planting potatoes in the conventional way requires a lot of labor for sowing and harvesting potatoes, and it is easy to cause dama...
