Problems solved by technology

[0002] At present, rice planting in many places in the southern rice region of my country is still a traditional agricultural farming mode with high labor intensity and high labor demand.
Along with rising labor prices, basic agricultural material prices, and lower rice purchase prices, the economic benefits of rice planting in many areas have declined, and even losses may occur due to random factors such as weather
These phenomena are not conducive to increasing farmers' income, reducing farmers' willingness to grow grain, and greatly affecting the economic ecology of rice planting and the safety of food production.

Embodiment 1

[0023] A method for harvesting and storing light-leaf rice, comprising the following steps:

[0024] (1) Harvest time selection: prepare for harvesting when 3 / 4 of the ears of rice in the field are yellow and ripe;

[0025] (2) Pre-harvest treatment: 7-10 days before harvest, drain the field water and dry the ground to facilitate the entry of large machinery; in case of cloudy and rainy weather, use sodium chlorate to dry up;

[0026] (3) Harvesting: when the moisture content of the paddy ears and grains is measured to be 19% by using the YT-L80 moisture analyzer, a full-feeding harvester is used for harvesting. feed;

[0027] (4) Post-harvest pretreatment: Aiming at the relatively smooth and hairless rice husk surface, which has a relatively large specific gravity and low wind resistance, the HYL-25 grain sorter is used to remove impurities, and the impurity content of the cutting sample is less than 2%;

[0028] (5) Drying: Use 50°C low temperature to air-dry the paddy in ...

Embodiment 2

[0031] A method for harvesting and storing light-leaf rice, comprising the following steps:

[0032] (1) Harvest time selection: prepare for harvesting when 3 / 4 of the ears of rice in the field are yellow and ripe;

[0033] (2) Pre-harvest treatment: 7-10 days before harvest, drain the field water and dry the ground to facilitate the entry of large machinery; in case of cloudy and rainy weather, use sodium chlorate to dry up;

[0034] (3) Harvesting: Use the YT-L80 moisture meter to measure the moisture content of the paddy ears and rice to 22%, use a semi-feeding harvester for harvesting, and after harvesting, smash the straw and return it to the field or bundle it for transportation for further processing. feed;

[0035] (4) Post-harvest pretreatment: In view of the relatively smooth and hairless rice husk surface of light-leaved rice, which has a relatively large specific gravity and low wind resistance, a gravity sorting machine is selected to screen the rice, and the imp...

Embodiment 3

[0039] A method for harvesting and storing light-leaf rice, comprising the following steps:

[0040] (1) Harvest time selection: prepare for harvesting when 3 / 4 of the ears of rice in the field are yellow and ripe;

[0041] (2) Pre-harvest treatment: 7-10 days before harvest, drain the field water and dry the ground to facilitate the entry of large machinery; in case of cloudy and rainy weather, use sodium chlorate to dry up;

[0042] (3) Harvesting: When the moisture content of the ear and rice is measured to be 18% by the YT-L80 moisture meter, a full-feeding harvester is used for harvesting. After harvesting, the straw is broken and returned to the field or bundled and transported for further processing. feed;

[0043] (4) Post-harvest pretreatment: Aiming at the relatively smooth and hairless surface of the rice husk of light-leaved rice, which has a relatively large specific gravity and low wind resistance, a color sorting machine is selected to screen the rice, and the ...

Abstract

The invention belongs to the technical field of rice planting, and particularly relates to a method for harvesting and storing smooth-leaf type rice. The method comprises the following steps: (1) selecting a harvesting period; (2) treatment before harvesting; (3) harvesting; (4) pretreatment after harvesting; (5) drying; and (6) storing. The suitable field harvesting period is guided by quantifying the field index rice panicle ripening degree and the rice panicle rice water content, a suitable mechanical harvesting environment is created through drainage and field drying, sorting and impurity removal are conducted by means of the smooth and hair-free characteristic of smooth leaf type rice husks, and the rice quality is reserved through low-temperature drying; a fingerprint database is established in combination with infrared spectrum to monitor the rice collecting and storing state in time, indexes are quantified as much as possible in the middle link, subjective judgment is reduced, operation threshold is lowered, mechanical operation is promoted, and efficiency is improved.

Background technique [0002] At present, rice planting in many places in the southern rice region of my country is still a traditional agricultural farming mode with high labor intensity and high labor demand. Along with rising labor prices, basic agricultural material prices, and lower rice purchase prices, the economic benefits of rice planting in many areas have declined, and even losses may occur due to random factors such as weather. These phenomena are not conducive to increasing farmers' income, reducing farmers' willingness to grow grain, and greatly affecting the economic ecology of rice planting and food production safety. [0003] After harvesting, rice can only enter the processing procedure after undergoing steps such as sorting, drying, and storage. Each link will have an impact on the quality ...
