The invention discloses a pelleting coating method suitable for tomato seeds. The pelleting coating method comprises the following steps: step 1, seed pretreatment; 2, a nucleation stage; 3, an enlarging stage; 4, a rolling stage; 5, a coloring agent and talcum powder are added, and the surfaces of the pellets are colored uniformly at the low rotating speed of 6-10 r / min; and 6, drying at 30-40 DEG C for 45-75 minutes until the water content of the pellets is less than or equal to 8%. According to the pelleting coating method for processing the tomato seeds, pesticide, fertilizer, a plant regulator, a water storage agent, an oxygen producer and some auxiliary materials can be orderly coated on the tomato seeds in a layered mode, the small tomato seeds can be amplified by dozens to hundreds of times through pelleting granulation, plant protection before sowing can be effectively achieved, field application with the fertilizer and the pesticide can be achieved, and the application range is wide. The purposes of protecting and strengthening seedlings and regulating plant growth are achieved, and favorable conditions are created for mechanical precision seeding, so that the purposes of saving a large amount of seeds, improving the yield and saving the cost are achieved.

The invention discloses a precise automatic control mechanism for sowing length, which belongs to agricultural machinery. A power transmission shaft with a follower pulley and a one-way ratchet is rotatably mounted on the upper side of a single frame assembly coaxially with a seeding drive shaft, a seeding power transmission disc with a pawl column is fixedly mounted on the end of the seeding drive shaft opposite to the power transmission shaft, the pawl and the torsion spring are sleeved on the pawl column, a two-way hydraulic cylinder and an anti-skid seeding drive wheel are mounted on the single frame assembly, a driving pulley is fixedly mounted on the anti-skid seeding drive wheel, a transmission belt is sleeved on the main and follower pulleys, a counting detection column is mounted on the outer end surface of the anti-skid seeding drive wheel, a counting sensor is mounted on the single frame assembly, and a wire connects the automatic controller with the counting sensor and the two-way hydraulic cylinder respectively. The mechanism realizes automatic and precise control of sowing length, is simple, convenient and fast to operate, saves seeds and reduces operating costs.

The invention discloses a soybean thin-planting high-yield planting method. The method comprises the following steps: 1) selecting soybeans with many branches, dense pods, no lodging, good stress resistance and convergent leaves as seeds; (2) selecting seeds by using a seed selecting machine or manually, removing diseased beans, bean halves, irregular soybeans and sundries, and ensuring that soybean seedlings emerge uniformly; 3) dressing the selected seeds with a soybean total coating agent to prevent and control diseases and insect pests; (4) according to the requirement of soybean varieties on accumulated temperature, the varieties with high accumulated temperature need to be sown early, and the varieties with low accumulated temperature need to be sown late; 5, a precision dibbler is used for sowing in a single seedling hole during sowing, about 2 jin of seeds are used per mu, about 20 jin of special soybean fertilizer is applied per mu, and 6, the sowing plant spacing ranges from 25 cm to 30 cm, soil covering is carried out by about 4 cm, pressing is carried out on the next day, soil moisture is raised, and weed killing sealing pesticide is sprayed on windy days.
