[0040] A method for planting selenium-enriched red seedling rice that improves the rate of polished rice, comprising the following steps:

[0041] 1) Selection:

[0042] Select the existing rice varieties, and use the rice screening machine with a rotating speed of 200-500 rpm to screen the rice to select the complete and plump rice;

[0043] 2) Site selection:

[0044] Seedling field: Select a field with good soil structure, and use agricultural machinery to carry out deep plowing of the land. The deep plowing depth is 20-50cm, and the compound fertilizer is applied. The compound fertilizer is 50-60% rapeseed cake, 20-30% grass ash, 1-3% potassium fertilizer, 1-3% phosphate fertilizer, and 2-4% urea are mixed and formed, and 800-1500kg of compound fertilizer is sprinkled per mu of land, and then the field surface is laid flat, and then divided into areas. The area of ​​each area is 1 -1.8 square meters, and the interval between each area is 10-40cm;

Abstract

The invention discloses a method for planting selenium-enriched red-seedling rice with am increased head rice rate. The method comprises the following steps of 1, seed selection, wherein an existing rice variety is selected, rice is screened through a rice screening machine with the rotation speed of 200-500 r / min, and the integral and full rice is selected; 2, land selection, wherein field parcels with good soil structure plates are selected as a rice seedling field, deep ploughing on land is conducted through agricultural machines, the depth for deep ploughing is 20-50 cm, 800-1,500 kg of compound fertilizer is sprayed to the field per mu, leveling on the field is conducted, then the field is divided into zones, the area of each zone is 1-1.8 m <2>, and the spacing between every two adjacent zones is 10-40 cm. According to the method, through the steps of selection of the full rice, selection of the selenium-enriched land, fertilizer cultivation on the rice seedling field and the land, spaced breeding and cultivation, subsequent fertilizer spraying, manual weed removal and pest removal through frogs, the health of the rice is ensured, the selenium content of the red-seedling riceis increased, the head rice rate of the red-seedling rice is increased, and the commercial value is higher.

Description

technical field [0001] The invention relates to the technical field of crop planting, in particular to a method for planting selenium-enriched red seedling rice that increases the rate of polished rice. Background technique [0002] Red seedling millet, as a mysterious and wonderful variety of millet, has a smooth taste and pleasant aroma when cooked. The stem diameter of red seedling millet is generally blood red during the growth period, while the stem diameter of ordinary yellow millet is generally green. Compared with traditional yellow millet, millet tastes better and is rich in nutrition. [0003] Traditional red seedling millet generally grows in the mountains, with irregular growth, many spikelets, and a high half-maturity rate, resulting in a low rate of whole milled rice, and it is generally self-grown and self-eating, with a low yield per mu. [0004] For this reason we propose a kind of selenium-enriched red seedling paddy planting method that improves the polis...
