Detailed Description
As shown in fig. 1, the sowing machine for improving the sowing speed and quality of the peanuts of the embodiment comprises: a seeding device and a tractor 1 for pulling the seeding device to advance in the field;
the seeding device comprises:
the frame 7 comprises a rectangular frame formed by welding square pipes, an upper bearing seat for supporting the roller device is arranged above the rectangular frame, a lower bearing seat for supporting the rotation of a wheel shaft of the land wheel 12 and a mounting shaft for mounting the furrow opener 10 and the soil covering device 9 are arranged below the rectangular frame;
a soil treatment system comprising at least a furrow opener 10 and a coverer 9; the furrow opener 10 is of a wing shovel type structure, and the soil entry angle of the furrow opener 10 is 60 degrees; the soil penetration angle refers to an included angle between the working plane of the furrow opener 10 and the ground; the too large soil-entering angle can cause the soil layer to be easily lifted and turned over, which is not beneficial to soil moisture conservation, and the too small soil-entering angle can cause the service life of the furrow opener 10 to be reduced, and the soil-entering angle adopted by the embodiment is 60 degrees. The reasonable soil penetration angle of the furrow opener 10 can solve the problems of large ditching resistance and large soil disturbance. The coverer 9 is of a fan-shaped frame structure and is fixed on the top surface of the furrow opener 10, and the arc bottom edge of the fan-shaped frame is the working surface of the coverer 9.
A seed discharging system including at least a seed tank 3 and a seed discharging mechanism for discharging seeds in the seed tank 3 into soil one by one at a set frequency; the seed box 3 is fixed above the frame 7 through a supporting arm made of two angle steels;

The sowing method for improving the peanut sowing speed and quality comprises the following steps:
s1. sun-drying seeds with shell before sowing to kill germs on the surface of the seeds, spreading the seed layer to sun-dry thickness less than 10cm, turning over periodically, and sun-drying for several days; the sun seeds before sowing can kill germs on the pod coat, enhance the water permeability of the seed coat, accelerate the water absorption speed of the seeds, promote the activity of enzyme, be beneficial to the conversion of nutrients in the seeds and improve the germination rate of the seeds. The seed maturity is poor, the seeds are affected with moisture during storage, and the sun-seeding effect is particularly remarkable. According to investigation, after the seed drying treatment, the peanut seedlings can emerge for 1-2 days in advance, and the yield is increased by 10-15%. When airing, the peanuts need to be thinly spread on a sunning ground in the morning of fine days, and are continuously aired for 2-3 days and often turned over.
S2, selecting large grains with full and undamaged seeds for seeding; during screening, the peanut pods are selected firstly, and the mixed fruits, rotten fruits and insect fruits are removed. And then, after husking, grading according to the size of seeds, sowing the seeds with large sizes together, sowing the seeds in the middle, and eliminating the seeds with small, shriveled, germinated and mildewed sizes. The seeds sowed in this way germinate neatly, and the phenomena that the big seedlings press the small seedlings and the big seedlings and the small seedlings compete for fertilizer and water are avoided.
s3. performing germination rate test on the selected seeds to ensure that the germination rate is more than 95%; the germination rate test is performed before sowing in order to ensure a high germination rate, so that the seedlings are uniform and strong after sowing.
s4. pre-treating the seeds to be sowed; the pretreatment method comprises seed dressing with a medicament, seed dressing with a microbial inoculum or seed dressing with a fertilizer. The seed dressing with the pesticide is a simple method with less investment and ideal prevention and control effect. The pesticide is used for dressing the seeds of the peanuts before sowing, so that the pest and disease damage can be reduced or prevented. Generally, carbendazim is fully and uniformly mixed with seeds according to 0.3-0.5 percent of the seed amount, and the mixture has good effect of preventing and treating stem rot and root rot. The rhizobia seed dressing for dressing the seed by the microbial inoculum can accelerate the formation of the rhizobia and enhance the nitrogen fixation effect. The seed dressing effect is better when the peanuts are newly cultivated on the red soil land, and the yield increase amplitude is more than 5%. Generally, 3000-3750 g of peanut rhizobium inoculant is mixed with proper amount of clear water and rice water into paste in each hectare before sowing, then the paste is poured into seeds, the seeds are gently turned and uniformly mixed, and the seeds are sowed along with the mixture (the mixed seeds need to be sowed on the same day), and direct sunlight is avoided after the seeds are sowed so as to avoid reducing the activity of rhizobium. The fertilizer is used for dressing seeds, 150-225 kg of calcium magnesium phosphate fertilizer can be used for dressing seeds per hectare before sowing, 0.2-0.3% ammonium molybdate solution or 0.1-0.2% boric acid water solution which is equivalent to 1/4 seeds can be used for uniformly spraying the fertilizer on the seeds, nutrient elements of the peanuts can be supplemented, the emergence rate is improved, and the plumpness rate can be improved.
s5. placing the treated seeds in the seed box 3 of said sowing machine; adjusting the seeding frequency of the seeding system to obtain proper seeding density; adjusting the height and angle of the furrow opener 10 to obtain a proper sowing depth;
s6. the seeder is used to complete seeding operation.
