Embodiment 1

[0021] This embodiment includes the following steps:

[0022] 1. Select medium-early-maturing varieties

[0023] It is advisable to choose high-yielding, high-quality, disease-resistant varieties with moderate growth period, strong regeneration ability, compact plant type, thick stems, medium tillering ability, appropriate plant height, strong internodes, well-developed root system, fertilizer resistance and lodging resistance. In this example, Jiafuzhan, Yongyou 2640 and Shenliangyou 676 varieties were selected.

[0024] 2. Fine land preparation

[0025] Field preparation requires dry plowing, fine land preparation, irrigation and raking to ensure that the muddy fields are flat and clean. After preparing the paddy field, open a ditch with a width of 2.7m. The ditch depth is 20cm, the ditch width is 25cm, and the border width is 250cm, so as not to affect the sowing and field management; The depth should be deeper than the furrow.

[0026] 3. Determine the sowing date, and...

Embodiment 2

[0044] This embodiment carries out direct seeding ratooning rice test research:

[0045] 1. Growth period of live-directed ratooning rice

[0046] In this example, Jiafuzhan, Yongyou 2640 and Shenliangyou 676 varieties were selected. All varieties were broadcast live on April 7, 2016. The growth period of the first season is 120-132 days, the growth period of the second season is 71-82 days, and the whole growth period is 193-203 days (Table 1). Among them, Jiafuzhan was cut by machine with low piles in the first season, and the ear was ready on September 13 in the regeneration season; Yongyou 2640 was cut by machine with high piles in the first season, but its regenerated ears were basically germinated from the axillary buds with inverted 4 and 5 nodes. , until September 17th; Shenliangyou 676 head season has a long growth period and is cut by high-stake machine. The regenerated ears are basically germinated from the axillary buds with inverted 2 and inverted 3 nodes, until ...

Embodiment 3

[0056] This embodiment is a study on the height of piles suitable for the first season of regenerated rice:

Abstract

The invention discloses a ratoon rice directly-seeding cultivation method. The method comprises the following steps: (1) selecting a medium and early-maturing fine variety; (2) finely preparing the soil; (3) directly seeding main rice crop by a precision machine at the appropriate period of the main rice crop from the last ten-day period of March to the first ten-day period of April, and arrangingthe heading and flowering phase of the ratoon rice ratooning season at the latest in the middle of September; (4) carrying out intermittent irrigation; (5) carrying out fertilization in the main cropping season; (6) applying a seedling fertilizer to the ratooning season; (7) harvesting the main rice crop by machine, wherein a low-pile machine harvesting mode is adopted for the main rice crop of ashort growth period variety and a high-pile machine harvesting mode is adopted for the main rice crop of a long growth period variety; (8) treating diseases and pests; and (9) removing weeds. According to the method, the agricultural production labor intensity is greatly reduced, the problems that the labor intensity for rice production is high and the benefit is low are solved. According to themethod, the rice production cost is reduced by 400 yuan per mu, and the labor for rice production is reduced by 70%, so that the production profits of the rice can be more than 500 yuan per mu, and the rapid improvement of the production mechanical level of the regenerated rice is realized.

Description

technical field [0001] The invention relates to the technical field of economic crops, in particular to a method for cultivating live-seeded ratooned rice. Background technique [0002] And ratooning rice is planted once and harvested twice, that is, after the first season of rice is harvested, the rice piles are used to re-emerge seedlings and grow ears, and then harvest another season of rice. Raising rice is a type of rice that has a long history of cultivation in China, dating back to 1700 years ago. Its characteristic is that after the ratooning rice is mature, only the upper 2 / 3 of the rice plant is cut off, and the rice ears are harvested, leaving the lower 1 / 3 of the plant and root system, fertilized and cultivated to allow it to grow again. A season of rice. [0003] In traditional technology, ratooning rice is mainly planted by traditional transplanting. With the transfer of rural labor to the secondary and tertiary industries, there has been a seasonal shortage ...
