Problems solved by technology

[0006] At present, in the production of perennial rice, the perennial rice piles are basically allowed to overwinter naturally in winter, which brings the following problems: there are many weeds around the rice piles, it is difficult to control soil temperature and humidity, the survival rate of rice piles is low, and the utilization rate of land resources is low. And other issues

Embodiment 1

[0041] Embodiment 1: Perennial rice intercropping broad bean during overwintering period

[0042] Intercropping broad beans in this embodiment, Yiliang County test field, sowing broad beans after the harvest of perennial rice on October 12, 2016, harvesting broad beans on April 10, 2017, and carrying out perennial rice pile finishing on April 25, 2017-27 1. To remove weeds, select the fresh broad bean variety Feng Broad Bean No. 18 with a growth period of 150 days. Specifically include the following steps:

[0043] (1) Harvesting of perennial rice: adopt harvester to harvest perennial rice, keep the rice pile, and the height of the rice pile is 15cm,

[0044] (2) Intercropping broad bean sowing: After the perennial rice is harvested, select the broad bean variety Fengcandou No. 18, which has a suitable growth period, high yield, excellent quality, and strong disease resistance, and whose growth cycle meets the needs of the perennial rice overwintering period. The growth peri...

Embodiment 2

[0050] Embodiment 2: Intercropping wheat in perennial rice overwintering period

[0051] Location: Yiliang test site; Altitude: 1600m; Climate conditions: North subtropical monsoon climate zone; annual average temperature 16.3°C, annual extreme maximum temperature 33.9°C, minimum temperature -6.2°C; average temperature of the hottest month is 21.7°C, coldest month The average temperature is 8.1°C.

[0052] In this example, wheat was intercropped in the experimental field of Yiliang County, and broad beans were sown after the harvest of perennial rice on October 9, 2016. Wheat was harvested on April 27, 2017, and perennial rice was harvested from April 30 to May 5, 2017. Pile tidying and weed removal; Yunmai 53, which is common in Yunnan, is selected as the wheat variety. It specifically includes the following steps: (1) Harvesting of perennial rice and retention of straw: the humidity in the field before harvest does not affect the filling and firmness of perennial rice, and ...

Embodiment 3

[0060] Embodiment 3: Perennial rice intercropping broad bean during overwintering period

[0061] High-quality perennial rice varieties were selected. Dry seedlings were raised on March 15, 2016 in the first season, and transplanted on April 20. The seedling age was 35 days. The transplanting density was 13,000 clumps per mu. field, harvested on October 12, 2016; Feng Broad Bean No. 18 was selected as described, and the broad bean sowing was completed on October 12, 2016, field management of broad beans was strengthened, and fresh broad beans were harvested in early April, 2017; as shown in Table 3, fresh broad beans The yield per mu has reached 1029.7 kg. Calculated at 1.8 yuan per kilogram, the output value per mu can be increased by 1853.4 yuan, which greatly improves the income of growers. On April 25, 2017, rice piles were sorted out and weeds were removed. On April 28, irrigation was carried out. On May 31, 7 points in one field were selected to investigate the survival ...

Abstract

The invention discloses a cultivation method for increasing the survival rate of rice piles by intercropping crops in the overwintering period of perennial rice. The method comprises the step that thecrops are intercropped around the rice piles of the perennial rice before the perennial rice enters the rice pile overwintering period, wherein varieties with the growth period and ecological suitability conforming to time and environment conditions of the overwintering period of the perennial rice are selected as the crops. The cultivation method for increasing the survival rate of the rice piles by intercropping the crops in the overwintering period of the perennial rice can fully improve the survival rate of the rice piles in the overwintering period of the perennial rice, achieve heat-preserving, moisture retention and nitrogen fixation functions on the rice piles of the perennial rice in winter, effectively improve the soil loosening degree and the fertility, control weeds and lay afirm foundation for high-yield efficient cultivation after overwintering of the perennial rice, the land utilization rate in winter is further improved, and the economic benefit of farmers is increased.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a cultivation method for improving the survival rate of rice piles by intercropping crops during the overwintering period of perennial rice. Background technique [0002] Perennial rice is a rice variety that can be harvested continuously for many years (multiple seasons) in one year. Perennial rice utilizes the axillary buds of its rhizomes (below the soil surface) after harvesting to survive the winter safely and re-grow, and restore normal rice production capacity in the next year (season), and then realize the production of perennial rice. Perennial rice is a new rice product. The measured output of single-cropping rice is 500 kg / mu-600 kg / mu, and the measured yield of double-cropping rice is 1,000 kg / mu-12,000 kg / mu (early rice + late rice). From the second production season From the beginning, it is no longer necessary to purchase seeds, seedlings...
