DEVELOPMENT OF HIGHLY EFFECTIVE MILLING CHISEL PLOUGHWITH SIMULTANEOUS LOCAL APPLICATION OF HYDROGEL

Abstract

The given article is related to agricultural engineering and the design of milling chisel ploughwith special working bodies for cutting water-absorbing slots with simultaneous introduction of hydrogel mixture into them was developed to increase moisture accumulation in soil in the article. Improved technologies and techniques are needed to improve the quality and quantity of crops, in particular cereals, in order to improve their production. Most of the territory of Kazakhstan belongs to the zone of risky agriculture. Every year there are droughts that significantly reduce cereal yields. Many farmers are making large amounts of fertilizer in order to increase yields. However, there is the problem of unsustainable use of fertilizers. Thus, most of fertilizers introduced into soil is washed into its lower layers and becomes inaccessible to plant roots. Therefore, we propose to use local application of hydrogel retention mixture to accumulate nutrients and soil moisture. Its granules are able to absorb liquid, in volume many times larger than their own, and hold it for a long time. For better nutrition of plants, we offer to enrich hydrogel with fertilizers. Possible machines for application of hydrogel mixture are considered in «Analysis of possible methods of application of hydrogel with fertilizers in soil». It is noted that there are no units capable of carrying out local application of granules with fertilizers together with milling chisel ploughinto seeding area in the modern system of machines. Existing machines allow the application of hydrogel in dispersed or subsoil way, and local application of granules together with fertilizers is used for the first time and allows place hydrogel with saturated fertilizers. The choice of optimal method of application of hydrogel mixture pellet was produced and the machine design for its implementation was developed on the basis of common and private methods.
