Problems solved by technology

[0004] Moreover, the paddy fields now use hydroponics and water consolidation, and the mud layer is getting deeper and deeper. After drying the fields, the soil compaction is serious and the soil fertility declines.

Embodiment Construction

[0016] Preparation before the year: Recycle the straw as feed or set fire to burn the broken grass spit out by the harvester after the rice is harvested before the year, and then grazing to eat up the grains in the field or fill them with shallow water to allow them to fully germinate, so as to prevent the growth of miscellaneous seedlings in the next year and cause a decrease in production . Then cultivate according to the following steps (based on one mu of field):

[0017] ①Soil preparation and fertilization: From April to May, cultivate in the state where the soil moisture in the field is suitable for planting dry crops. Regardless of whether it is machine-organized or animal-organized, it is required to apply 38 kg of ammonium bicarbonate per mu as the base fertilizer before preparing the soil, and then apply compound per mu. Fertilize 28 kilograms and then adjust the land again, requiring the soil block to be thick inside, thin outside, and flat on the surface; finally, ...

Abstract

The invention provides a full set of dry-finishing direct-sowing rice cultivating technologies which can save labor, increase output, resist fall-down and improve soil and the land farming mud layer. As the dry-cultivation and the dry-finishing are adopted, the soil has good crumb structure, good hydroscopic property and good water permeability, which facilitates to ensure that the seedlings can tiller earlier and more at lower positions and the basic seedlings are sufficient; a high-yield seedling rack can be formed easily without transplanting and seedling mitigating and the mature period can be advanced for 7-10 days. By adopting the technology, the requirement of the rice for water in the middle and last period is looser, the maturing rate is high, the kernel is heavy and big and the land farming mud layer can be kept in an optimum state for ever.

Description

technical field [0001] The invention relates to a rice planting method, in particular to a rice cultivation technique in which rice seeds are directly sown in the field after drying the rice field. Background technique [0002] As everyone knows, the majority of farmers have basically adopted this important production link of transplanting on the paddy rice cultivation method. Then let's start with transplanting: transplanting increases the process of breeding, pulling and transplanting, which makes the whole production process require a lot of labor, especially the two links of pulling and transplanting are more labor-intensive. type of work. Transplanting has adverse effects on seedlings, especially in the current situation of insufficient rural labor force and aging labor force, which may become worse with the increase of labor volume. Because transplanting means adding a process, it also increases the amount of labor, and in most cases, this process is added after the ...
