Embodiment 1

[0032] A cultivation method for interplanting Chinese yam with early rice, comprising the following steps:

[0033] (1) Land selection and land preparation: choose a sandy loam field with deep soil layer, high organic matter content, good drainage and irrigation conditions, and good air permeability as the planting site. After the harvest of the previous crop, chop the crop straw to 4 cm, and plow the soil 30 cm , apply 5kg of farmyard manure and 20kg of plant ash per mu as the base manure, before planting, shallow plow once more, then rake and flatten, make the planting furrow in the north-south direction, upland rice and Chinese yam are planted on the car surface; the planting furrow The width is 120cm, the length of the furrow is 500cm, the distance between the furrows is 35cm, and the height of the raised furrow is 35cm;

[0034] (2) Variety selection: select high-quality varieties of hybrid upland rice with good disease resistance and relatively early maturity; select tub...

[0046] A cultivation method for interplanting Chinese yam with early rice, comprising the following steps:

[0047] (1) Land selection and land preparation: choose a sandy loam field with deep soil layer, high organic matter content, good irrigation and drainage conditions, and good air permeability as the planting site. After harvesting the crops of the previous season, chop the crop straw to 5 cm, and plow the soil to 45 cm. , apply 15kg farmyard manure and 30kg plant ash per mu as base manure, before planting, plow shallowly once more, then rake and flatten, make planting furrows with north-south direction, upland rice and Chinese yam are planted on the car surface; said planting furrows The width is 150cm, the length of the furrow is 800cm, the distance between the furrows is 55cm, and the height of the raised furrow is 40cm;

[0048] (2) Variety selection: select high-quality varieties of hybrid upland rice with good disease resistance and relatively early maturity; selec...

Embodiment 3

[0060] A cultivation method for interplanting Chinese yam with early rice, comprising the following steps:

[0061] (1) Land selection and land preparation: Select a sandy loam field with deep soil layer, high organic matter content, good drainage and irrigation conditions, and good air permeability as the planting land. After harvesting the crops of the previous season, chop the crop straw to 4.5-5cm and turn it over. The soil is 35-40cm, and 10-15kg of farmyard manure and 25-30kg of plant ash are applied per mu as the base fertilizer. On the side of the car; the width of the planting border is 130-150 cm, the length of the border is 700-800 cm, the distance between the borders is 35-45 cm, and the height of the planting border is 35-37 cm;

[0062] (2) Variety selection: select high-quality varieties of hybrid upland rice with good disease resistance and relatively early maturity; select tubers harvested in the same year, free from pests and diseases, without mechanical dama...

Abstract

The invention relates to a cultivation method for interplanting early season rice with Chinese yams. The method comprises the steps of land selection and preparation, variety selection, seed soaking and germination accelerating of Chinese yam seeds, sowing, enough Chinese yam base fertilizer application, field management, harvesting and the like. By means of the characteristics that early season rice plants are short and upright and the light requirements of the seedling stage after sowing is conducted on the Chinese yams are low, scientific and reasonable internplanting is conducted on the early season rice and the Chinese yams, the problems that pest and disease damage is caused by continuous cropping, so that the Chinese yam yield is low, and the quality is poor are solved, the yield can be increased, the early season rice and the Chinese yams can come into the market in advance, and the good economic benefit is obtained; field management is conducted in the mode of combining intertillage weeding, topdressing and pest and disease damage control is adopted, reasonable nutritional ingredients can be provided for the early season rice and the Chinese yams, and meanwhile the pest and disease damage control effect is achieved; the control effect is significant, and the phenomenon that chemical pesticide is used for treatment is avoided.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and in particular relates to a cultivation method for interplanting Chinese yam with early rice. Background technique [0002] Upland rice, drought-tolerant, cultivated rice suitable for upland cultivation, also known as upland rice, generally refers to cultivated rice that can adapt to growing in boundless drylands, slopes and arid ecological environments, and is a variant of upland rice. It is a different concept from desert upland rice. Upland rice has the characteristics of drought tolerance, barren tolerance, and wide adaptability. Under the circumstances of global population expansion, climate warming, water shortage or large-scale drought, the development and utilization of upland rice has special significance for ensuring global food security. : (1) Upland rice upland farming can make full use of natural precipitation, so that the upland rice planting is no longer restricted by ...
