Abstract
Over the past two years, decrease in potato yield has been observed in the Moscow region. One of the main reasons is unfavorable weather conditions. To obtain a guaranteed yield, as well as to improve the quality of products, it is necessary to carry out reclamation works, including additional irrigation. Creation of the optimal water - air balance of the plant throughout the entire growing season will increase productivity, and improve the quality of agricultural products. Drip irrigation is the most economical method of irrigation, but its widespread use is hindered by the high proportion of manual labor when installing the drip tape. A mechanized method of laying the drip tape by placing the working equipment on the Grimme GF-75/4 comb former is offered. The existing methods for determining the irrigation rate do not consider the parameters of the humidification circuit, which leads to excessive irrigation and additional losses of irrigation water. The paper offers a method for determining the irrigation rate considering the shape of the humidification circuit and its geometric parameters.
Highlights
In the Moscow region, after the record potato harvest in 2019, which amounted to 460 tons, there has been a decline [1]
The working equipment of the drip tape stacker was installed on the Grimme GF-75/4 comb former and the drip tape was laid on the experimental site of the Field Experimental Station of the Russian State Agricultural University named after K.A
Creation of the specialized machine for placing drip tape in the potato comb will expand the application of this irrigation method
Summary
In the Moscow region, after the record potato harvest in 2019, which amounted to 460 tons, there has been a decline [1]. Potatoes with a diameter of over 55 mm are most in demand, and until last year the share of such products intended for food purposes was about 80 % [4, 5] Last year, this figure dropped to 50 %, and economy class chain stores were forced to make concessions, the rest switched to imports. This figure dropped to 50 %, and economy class chain stores were forced to make concessions, the rest switched to imports This year, the region will not receive part of the planned harvest, and imported products may appear on store shelves in the fall, and not in the spring, as in previous years
