Problems solved by technology

⑤Under the background of my country's "double reduction" action and zero growth in chemical fertilizer use, the application of manure and other organic fertilizers will increase significantly, but the application of manure will be more difficult and time-limited when paddy fields are covered with water. Dry planting seedlings and dry farming can overcome the problem of difficult application of water-based organic fertilizers
In areas with two crops a year, such as Shandong, the most common is the rotation of rice and winter wheat. This type of rice-wheat rotation is planted all year round, and the mode is single, which makes the root rot and scab of wheat more and more serious.

Embodiment 1

[0037] Rice dry planting and onion crop rotation under the mode of returning full amount of rice straw to the field on the clay soil of Linyi, the main rice production area in Shandong

[0038] The dry-planted rice and onion seedlings of the method adopt the same seedling-raising tray and the same planter to raise seedlings successively, and the dry-planted rice and onions are planted by the same transplanting machine, and the steps are as follows:

[0039] (1) Raising rice seedlings for dry planting: On May 15-20 in Shandong area, a seedling tray was used to raise rice seedlings, and the seedling raising period was 30 days. body, the pot body is located in the disc body, the disc body of the seedling plate is provided with 5 grooves, the support body is located in the grooves, the diameter of the upper mouth of the pot body is 2.5cm, the diameter of the bottom surface of the pot body is 2.4cm, and The height is 2cm; the lower surface of the pot body is equipped with a permeab...

Embodiment 2

[0066] With the paddy rice described in embodiment 1 and onion same machinery upland integrated crop rotation method, carry out by the method and the step of embodiment 1, difference is:

[0067] In step (3), a transplanting machine is used for dry rice seedling transplanting; the row spacing of dry rice planting is 30 cm, the plant spacing is 18 cm, the depth is 3.0 cm, and the number of rice planted is 17,000 / mu.

[0068] In step (4), onion planting is carried out in early November after site preparation. The transplanting machine of step (3) is used for onion planting. After the transplanting machine adjusts the distance between plants to 10cm, it is directly applied to onion dry planting. The dry planting step procedure is as follows: Rice in progress.

Abstract

The invention relates to a rice and onion integrated rotation method using the same machine in dry farmland. According to the method, the same transplanter is utilized, and dry farmland rice pot seedlings and onions are subjected to rotation in special crops of rotation in a double cropped region. In the rotation process of dry farmland rice and the onions, seedling raising pot trays and the transplanter can be annually used, the same equipment, the same field and the same machine are used for seedling raising and planting, mechanical integration is achieved, the investment cost is reduced, the problems that traditional rice-wheat rotation is short in rotation crop conversion period and steeping field straw floats are changed, the rice yield is increased, the output value of the onions isimproved, meanwhile, a lot of water is saved, and diseases of rice are greatly reduced.

Description

technical field [0001] The invention relates to an integrated crop rotation method for rice and onion in the same dry field with the same machine, and belongs to the technical field of agricultural crop cultivation. Background technique [0002] Existing paddy rice planting is paddy field transplanting, and the transplanting mode has artificial transplanting, artificial throwing, mechanical transplanting and mechanical throwing and so on. The irrigation volume of rice is more than that of other upland crops, but the water consumption of rice fields is mostly used for hydroponic field before transplanting and evaporation between trees and field infiltration during rice growth. In fact, its physiological water requirement is not much. About 1 / 3 to 2 / 3 is used for farming and ecological water, which has great potential for water saving (Xiao Yujiang, 1985; Wu Boshun et al., 1985). The irrigation quota during the growth period of dry rice is 3000m per hectare 3 A higher yield ...
