Field method for producing seeds by hybrid rice parents transplanting and harvesting integrated machine

Abstract

The invention relates to a field method for producing seeds by a hybrid rice parents transplanting and harvesting integrated machine. The method includes the following steps: 1. setting aside an enclosure with a width of r around a seed production field block to plant female parents, and setting aside an interval between an outer female parent enclosure and an inner planting enclosure; 2. plantingmale parents and female parents at intervals inside; 3. calculating the length and width of the whole field; 4. marking the inner male parent planting enclosure, and transplanting the parents throughthe machine; 5. pollinating by an unmanned aerial vehicle; and 6. harvesting the outer female parents firstly, then harvesting the inner male parent enclosure, and finally harvesting the remaining female parents. The method can realize the high integration of transplanting and harvesting the hybrid rice parents through the machine, reduce the labor intensity in the whole process, improve the production efficiency and benefit, and at the same time can further increase the female parent harvest yield and improve the seed production benefit.

Description

technical field [0001] The invention relates to a method for planning, planting, harvesting, and seed production in the field, in particular to a field method capable of realizing the integrated machine-transplanting and machine-harvesting of hybrid rice parents. Background technique [0002] Sichuan is a major rice planting province, and it is also a major hybrid indica rice production province. With the lack of rural labor force, the rice seed production industry is gradually developing towards mechanization. At present, although many people are proposing the mechanization of the whole process of hybrid rice seed production, since the parent plants have always been planted in boxes during seed production, and the number of male parents is relatively small compared with that of female parents, generally only 1-2 rows, the so-called The whole process of mechanization has realized the mechanization of some links. Especially in the harvesting process, the male parent is gene...

Problems solved by technology

Especially in the harvesting process, the male parent is generally cut off manually first and then the female parent is harvested by machine. If this method is used on a large scale, it is still very labor-intensive, and in fact the whole process has not been fully mechanized; or some experts have previously A harvester that can harvest two rows of male parents is mentioned, but due to the narrow application area, it cannot be widely used

This is because the machines used solely for hybrid rice seed production have been discontinued due to narrow application, high cost, and low sales. Therefore, mechanized seed production must be connected with large-scale production to go further.

Secondly, since the parents have always been planted in boxes spaced apart from each other, especially in the harvesting process, for example, the planting box can introduce a large machine with a cutting width of 1.5-2.0 meters in production, but it cannot turn around. It is difficult to move across the female parent to another male parent, unless there are open spaces for the machine to turn or a wide traction path on both sides perpendicular to the planting box, but this is unrealistic
