Embodiment Construction
[0041] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0042] A method for whole-process mechanized cultivation of rice stubble and wheat, aimed at a rice-wheat rotation system, comprising:
[0043] 1. Straw returning to the field
[0044] Dry the field 5 to 7 days before rice harvest to reduce the soil moisture content in the field. Harvest rice with Kubota combine harvester, stubble height ≤ 25cm, crush rice straw while harvesting rice, and then use straw returning machine to crush and return the remaining straw in the field, requiring more than 85% of the straw length after crushing...

The invention discloses a method for mechanized cultivation of rice stubble and wheat throughout the whole process. Aiming at the rice-wheat rotation system, the method comprises: (1) drying the field before harvesting rice, and mechanically harvesting rice; Different soil preparation methods are used for the water quantity; (3) Different seed treatment methods are used for the selected seeds for different degrees of disease areas; (4) The suitable sowing date is determined according to the climate, variety type, and soil moisture, and the planting is carried out within the suitable sowing period. Sowing, using a sowing machine that integrates sowing, fertilization, and suppression, the sowing depth is adjusted according to the soil moisture, and the fertilizer base is applied at the same time when sowing, and the sowing depth is adjusted according to the soil moisture; (5) field management; (6) in wheat wax Harvesting is carried out from the late ripening period to the full ripening period, and the crushed wheat straw is returned to the field. The method of the invention can establish a systematic mechanized cultivation technique, improve the planting quality of rice stubble and wheat, and realize high yield.
Description
technical field [0001] The invention relates to a method for cultivating rice stubble wheat, in particular to a method for whole-process mechanized cultivation of rice stubble wheat. Background technique [0002] Rice-wheat rotation is the main food crop production mode in the middle and lower reaches of the Yangtze River Plain. This mode is a multiple cropping mode in which wheat is sown after harvesting rice to achieve two crops a year. The rice-wheat rotation mode has a long planting history in this region, but the wheat season yield has always been at a low level, and the average yield per unit area is about 20% lower than the national average level, and about 50% lower than that in the Huang-Huai-Hai Plain wheat region. The reasons for the low wheat production in this region mainly include the following aspects: [0003] (1) Due to the long-term flooding of the previous crop of rice, the soil in the field is wet and sticky, and it is difficult to plow and prepare the l...
