Wheat is an important food crop in China, and the wheat precision planter is the most commonly used agricultural seeding device in wheat growing areas, which effectively improves the efficiency and quality of wheat sowing, and provides a significant increase in wheat yield. This article introduces in detail the environmental requirements, inspection adjustment and precautions for wheat precision planter for your reference.
Environmental requirements for precision sowing of wheat
To achieve precise seeding of wheat, there must be certain requirements for the environment to be planted. Precision sowing is suitable for high-yield plots with good soil foundation. The plots should be loose, the ground should be smooth without obvious soil, and the base Fertilizer must be applied, because only good soil can produce good quality wheat.
The seeds selected for precision sowing of wheat must also be high-yield varieties with good individual performance. Before seeding, the seeds should be cleaned with a suitable long-hole sieve to ensure the seed particles are full and the germination rate is high. In order to prevent the occurrence of pests and diseases, it is best to treat the seeds with drugs before sowing. In addition, due to the low seeding rate of finely sown wheat, the population is basically increased by tillering, so it is necessary to carry out early seeding according to the temperature and the ground temperature according to the solar terms.
Inspection and adjustment of the seed drill before planting
Appropriate inspection and adjustment of the planter should be carried out before intensive planting of wheat to ensure that the planter is in good working order, thus ensuring the quality of the seeding. It is necessary to fill the oil filling points in time before planting in order to fully lubricate the running parts. Repair and replenish lost and damaged parts in a timely manner. In order to prevent the soil from sticking to the chain and increase the damage of the parts, it is also necessary to pay oil to the gear chain and the chain when filling the oil.
Before planting, it is necessary to check whether the working lengths of the rows of seed wheels are equal. Whether the rotation of the disc opener, the seeding shaft and the fertilizer shaft is flexible, it is necessary to make the working length of each row of seed wheels equal, and the broadcast amount adjustment mechanism is flexible. Sliding and air movement phenomenon; the disc opener disc rotates flexibly, does not sway, and does not rub against the opener body, so as to ensure the seeding quality.
Before and after each shift, the soil in each part should be cleaned, paying special attention to removing dirt and oil from the transmission system. At the end of each shift, the fertilizer in the fertilizer tank should be cleaned to prevent the fertilizer from corroding the fertilizer tank and the fertilizer discharge site.
Before sowing, it is also necessary to adjust the left and right level of the precision planter and the level of the front and rear according to the situation of the planting, and to adjust the lifting height and the sowing depth of the planter appropriately. The left and right horizontal adjustment needs to lower the seeding machine so that the blade tip of the opener is equal to the ground height. If the height from the ground is inconsistent, the suspension mechanism pull rod should be adjusted to make the seeder horizontal. When adjusting the front and rear level, the seeding machine should be lowered to the required depth of sowing, so that the drive shaft of the seeding machine is level before and after. If it is not horizontal, the upper rod should be adjusted. The lifting height of the planter should not be too large. Generally, when working in the field, just raise it to the tip of the knife 20 cm from the surface. Finally, when the seed drill reaches the required sowing depth, the positioning adjustment handle is blocked by the positioning device so that it drops to the same depth each time.
Precautions when planting
When planting with a wheat intensive seed drill, it is also necessary to be familiar with the operational requirements during sowing to ensure the quality of the sowing. For example, the first thing that needs to be done when planting is that the planter can travel straight at a constant speed. It can't be slowed down or stopped midway to prevent the occurrence of replaying. In order to prevent the opener from being blocked, the lifting and lowering of the planter should be operated in the process of going backwards. The planter should be lifted when turning. When planting, we must first traverse the ground, so as not to harden the ground, causing the planting to be too shallow. When working in the planter, it is strictly forbidden to reverse or turn sharply. The lifting or lowering of the planter should be carried out slowly to avoid damage to the machine. Once the conveyor structure of the planter is found to be faulty, it must be disposed of after parking. In addition, the seeder should pay attention to the amount of seeds in the seed box should not be less than 1/5 of the volume of the seed box, but also ensure that no other foreign matter enters the seeder and blocks the seeding port.
Dispersant Agent mainly for textile industry.
Mainly used to coloring for vat dyes, reactive dyes, acid dyes, acid staining pad or pigment pad dyeing of the dispersing agent, as a auxiliaries for vat dyes's powder or sizing agent. Also used staining to levelling agent and auxiliary tanning agent in leather industry. Can also be used for textile printing and dyeing, pesticides as dispersing agent, papermaking, electroplating additives, latex, rubber, construction, water-soluble paint, pigment dispersant, oil drilling, water treatment agent, carbon black, printing ink dispersant.
