Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention aims to provide a precision sowing method for hybrid rice and design related mechanical equipment to solve the problems of low seed quantity, low sowing quantity, single seedling transplantation and seedling quality of hybrid rice (including super rice). High, can be matched with machine transplanting, and is conducive to high efficiency, ecology, environmental protection and other issues. This sowing method sows evenly and has high sowing efficiency. The dosage is more suitable for sowing seedlings in hybrid rice machine transplanting trays

Embodiment 1

[0085] A hybrid rice machine transplanting tray seedling raising precision seeder, comprising a fixed frame 1, a transmission device composed of a conveyor belt 24 and a motor 22, a seedling raising tray 23 arranged on the conveyor belt 24, and sequentially arranged on the fixed frame 1 along the advancing direction of the conveyor belt 24 The bottom material storage tank 2, the seed storage tank 3 and the cover material storage tank 4 above; it is characterized in that a buffer bucket 6 is provided under the bottom material storage tank 2, the seed storage tank 3 and the cover material storage tank 4; The bottom of the buffer bucket 6 is provided with a double-bottomed uniform vibration plate 16; the double-bottomed uniform vibration plate 16 includes an upper fixed base plate 10, a lower movable base plate 11 connected below the upper fixed base plate 10, and a lower movable base plate 11 arranged on the upper fixed base plate 10. The vibrating rod 19 and the vibrator 12 conn...

Embodiment 2

[0105] In 2013, a large grain household in Longhui County, Hunan Province had 113 mu of rice fields, and adopted the four-control precision seeding method for hybrid rice machine-inserted seedling raising.

[0106] 1. Preparatory work:

[0107] 1. The selected variety is super hybrid rice Y 2 No. 1, the amount of seed used per mu is 0.75 kg, and 85 kg of rice seeds are purchased.

[0108] 2. There are 23 floppy disks for seedling cultivation per mu, and a total of 2,600 floppy disks are purchased

[0109] 3. Use 2 kg of substrate for each tray, and 5,200 kg of self-made seedling raising substrate.

[0110] 2. Seed soaking and germination:

[0111] 1. The time of sowing is April 10. Six days before soaking, put the seeds in the sun on a bamboo plaque for one day, then pack the sun-dried seeds into bags and put them in a dry, shady place to cool thoroughly.

[0112] 2. Put the rice seeds in 5 large mesh bags, wash the rice when soaking the seeds, mainly to remove impurities, ...

Abstract

The invention discloses a hybrid rice machine transplanting disc rice seedling raising four-control precision seeding method. The method comprises the following steps of (1) performing pretreatment on seeds; (2) preparing a rice seedling raising disc and a rice seedling raising matrix; (3) seeding by a multifunctional seeder, controlling the seed amount per mu, controlling the seeding amount per disc, controlling the rice grain falling amount per square centimeter, and controlling the rice seedling raising matrix amount per rice seedling raising disc. The method has the following advantages that (1) precision quantitative seeding of hybrid rice is realized by the multifunctional seeder, four types of control are realized, seeding is uniform, and the seeding efficiency is high; (2) due to the fact that the matrix is mechanically and uniformly filled, the utilization rate of resources is improved while the using amount of the medium is reduced; (3) a full, uniform and strong hybrid rice seed seeding process is realized, and a foundation of post field management is laid; (4) mechanization of the whole seeding process is realized, the labor intensity is reduced, and the labor efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of hybrid rice sowing, and in particular relates to a sowing method of hybrid rice machine-transplanted seedling raising. Background technique [0002] The sowing method in the prior art basically includes steps such as pre-treatment of seeds, preparation of seedling trays and seedling substrates, sowing, and field management. There are various seeding equipment. For example, patent application 200420079486.4 discloses an automatic seeding machine for plastic tray seedling cultivation. , it is equipped with an assembly line device composed of a conveyor belt. The plastic plate is placed on the conveyor belt. On the frame above the plastic plate, a base soil spreader, a seed spreader, and a cover soil spreader are arranged in sequence along the forward direction of the plastic plate. and soil rollers. The equipment can realize the mechanization of plastic disc sowing, from an empty disc to a complete disc, f...
