Advantages of spraying pesticides with a big tractor for sale
Although the big tractor for sale is a kind of more complicated machine, its type and size also vary, but they are composed of three major parts of engine, chassis and electrical equipment, each of which is indispensable. There are three main advantages to using a big tractor for sale to spray pesticides:
(1) it can ensure even drug application and improve defoliation effect. The most commonly used defoliant for cotton farmers is a plant growth regulator based on thibenuron, which is a contact agent. The big tractor for sale has a boom, the amount of water used per mu is generally controlled at 30 -50 liters, which makes it easier to ensure that the upper, middle and lower leaves of cotton are evenly sprayed, and is beneficial to reducing the times of application and increasing the rate of defoliation.
(2) the strong acidity of ethephon, diluted by large amount of water, greatly reduced the effect of thibenuron. The process of ripening and defoliation in machine-picked cotton requires that defoliant and ethephon should be used together. Ethephon is a strong acid agent (PH = 0.7-3) , will not degrade thibenuron, does not affect the effect of defoliant play.
(3) few branches were hung on the charred leaves. It has been proved by a lot of practice that because of the reasonable concentration of the big tractor for sale, the risk of hanging branches on the scorched leaves in cotton field is obviously lower than that by UAV, and there is little or no hanging branches on the scorched leaves in cotton field.
