Problems solved by technology

Due to the shallow root system of rice in the direct seeding field, it is easy to lodging in the later stage, and if the seeding is too deep, the emergence rate of rice will be seriously reduced

Embodiment Construction

[0024] The present invention is further illustrated below by way of examples.

[0025] A rice direct seeding planting method, comprises the following steps,

[0026] Soil preparation: plowing and dividing the furrows, the width of the furrows is 2 to 3 meters, and the height difference between the furrows is required to be no more than 1 inch. After the mud settles, the seeds are planted, and the ditches are equipped to ensure that the water surface is just below the furrows or the fish furrows are flush;

[0027] timely sowing

[0028] 1), select seeds, select unfulfilled or broken rice seeds by sieving, and then remove empty and shriveled seeds by floating method;

[0029] 2), sowing date and sowing amount. Direct-directed rice requires sowing when the daily average temperature rises steadily to 12-14°C. The sowing date of early rice is mid-April, and the sowing date of single-cropping rice is early May. The sowing amount of conventional early rice is 3-4 kg, and the seedi...

Abstract

The invention discloses a rice direct-seeding planting method and relates to the technical field of rice planting. The method includes following steps: preparing land; seeding and selecting seeds at proper time; determining seeding period and seeding quantity; blending seeds: using a disinfecting germination accelerating agent of 2-4 times in weight for seed blending of selected seeds, wherein the disinfecting germination accelerating agent comprises, by weight, 90-110 parts of dry sludge soil, 3-5 parts of carbendazim, 30-40 parts of gelatin, 20-30 parts of bentonite, 1-3 parts of jasmine oil, 0.01-0.05 part of galanthamine hydrobromide, 0.004-0.006 part of corn flour, 0.004-0.006 part of gibberellin and 0.005-0.007 part of naphthylacetic acid; sun-drying the seeds immediately after seed blending; seeding: quantitatively seeding before seeding, setting seeding depth to 3-5 cm, and timely thinning and thickening when each seedling has 2-3 leaves to enable plants to be distributed uniformly. The rice direct-seeding planting device is good in germination accelerating effect, high in seedling emergence rate, low in growing tendency, deep in root, high in lodging resistance and earring rate and conducive to increasing yield.

Description

Technical field: [0001] The invention relates to the technical field of rice planting, in particular to a direct seeding planting method of rice. Background technique: [0002] The direct seeding cultivation technology of rice refers to a cultivation method in which rice seeds are directly sown in the field without raising seedlings and transplanting. As a cultivation technique, rice direct seeding has a long history in my country. As early as in ancient times, rice cultivation in my country was dominated by direct seeding, but due to the backwardness of science and technology at that time, the corresponding supporting cultivation techniques could not keep up, and it was gradually replaced by seedling raising and transplanting. By the 1980s, with the advancement of science and technology, the deepening of reform and opening up, the implementation of the joint production contract responsibility system in rural areas, the vigorous development of secondary and tertiary industr...
