Embodiment approach

[0029] Implementation plan: the implementation is divided into two treatments, (1) the control, that is, the conventional transplanting method, and (2) the full amount of the placed rice straw returning to the field. In 2007-2008, the implementation area in Jiangdian Village, Licheng Town was 167 mu; in 2008-2009, the implementation area was 1,065 mu in Seyang Village, Zhucheng Town. The specific operation is: choose a dry land with loose, fertile soil, drainage and watering to make rapeseed field. Seedling field and big field are done full rape seedling field by 1:6 ratio. On September 25th, sow in good time, the seeding rate in the seedling field is 0.5-0.6kg per mu, the seedlings in the second leaf stage, the uniform seedlings in the three leaf stage and the fixed seedlings (72-90 plants / m 2 ), keep 50,000 seedlings per mu, and spray 200ppm paclobutrazol to cultivate short and strong seedlings.

Abstract

The invention discloses a rape no-tillage place-transplanting total straw application high production and high efficiency method, relating to the rape cultivation technology; in the technology, after rice is harvested, a rake is used for hoeing furrows and fixing ridges, the width of the ridge surface is 90cm, the width of the furrow is 30cm, the wide row spacing and narrow inter-plant distance technology is adopted, two rows of the plants are planted in each ridge, the inter-plant distance is 15-18cm, rape seedlings are placed close to the ridge soil tightly, the roots of the seedlings are pressed by soil blocks, when one ridge is planted, the straw is paved on the ridge surface, and the straws are pressed by soil in the furrow. Compared with the technology which adopts normal transplanting technology, the production is increased by 30.1 kilograms / acre by adopting the parcel of rice field, the production is increased by 18.38 percent, 3-4 workers are reduced, and 150-200 yuan / acre cost is saved. By adopting the rape no-tillage total straw application technology, the problem of environment pollution caused by firing and discarding the straws is solved, the organic matter content of the soil is increased and weed growth is reduced by adopting straw coverage. The technology has simple operation and good promotion and application prospect.

Description

technical field [0001] The invention relates to a high-yield and high-efficiency method for full-scale returning of rapeseed with no-tillage and swing-planting rice straw, and belongs to the technical field of rapeseed cultivation. Background technique [0002] Rapeseed is one of the most important oil crops in my country, ranking first in the world in both area and output. On the whole, the traditional cultivation techniques of rapeseed in my country aim to increase the yield per unit area, take intensive cultivation as the core, and artificial labor as the main line. High-yield cultivation techniques mostly adopt the method of artificial seedling cultivation and hole transplanting, which requires a large amount of labor. Since the reform and opening up, with the transfer of rural labor force, the idea of ​​centering on economic benefits has been deeply rooted in the hearts of the people. Rapeseed cultivation technology must solve the contradiction between high yield and h...
