Abstract

Currently used in Russia traditional technologies of rice cultivation with continuous or short-term flooding of rice paddies are ineffective for a number of factors, the main of which are the high cost and high labor intensity of rice production. Research in the field of rice cultivation has identified four main promising technologies that can reduce the cost of rice produced: 1 - intermittent flooding; 2 - periodic moistening without creating a layer of water; 3 - sprinkling, including surface irrigation; 4 - drip irrigation. The purpose of our research was to develop a new drip irrigation rice cultivation technology adapted for the climatic and soil conditions of the Krasnodar Territory. As a result of the research carried out, a drip irrigation technological scheme was developed and implemented for LLC “Chernoerkovskoye” of the Slavyansky district of the Krasnodar region. The developed scheme of rice cultivation on drip irrigation has proven its effectiveness, expressed in improving the reclamation state of soils, increasing the profitability of production and increasing the yield, reducing the irrigation rate, the cost of rice grain and labor intensity.

Highlights

Numerous foreign and domestic studies of the cultivation of both dry and aerobic rice show [1-8] that the issue of transition from flooded rice to aerobic rice is relevant and should be worked out in accordance with all modern ecological and reclamation requirements that are currently imposed on production agricultural products, including rice culture [9, 12]
High interest among rice producers, as a rule, is associated with the further impossibility and/or inefficiency of rice production using the traditional technology of rice cultivation with continuous or shortened flooding of rice paddies due to the lack or insufficiency of the required volume and / or quality of irrigation water, lack of the necessary technical support for the implementation of all agrotechnical methods necessary for the normal cultivation of rice, reducing the soil reclamation state to a level at which the introduction of organic and mineral fertilizers does not compensate for the low soil fertility and is ineffective and economically inexpedient [13-16]
Long-term practice of rice cultivation on rice irrigation systems of the Krasnodar Territory revealed the urgent problem of a high degree of weed infestation in rice paddies, which in turn requires high expenditures of financial and labor resources to obtain planned yields without reducing the reclamation state of soils [19-20]

Summary

Introduction

Numerous foreign and domestic studies of the cultivation of both dry and aerobic rice show [1-8] that the issue of transition from flooded rice to aerobic rice is relevant and should be worked out in accordance with all modern ecological and reclamation requirements that are currently imposed on production agricultural products, including rice culture [9, 12]. High interest among rice producers, as a rule, is associated with the further impossibility and/or inefficiency of rice production using the traditional technology of rice cultivation with continuous or shortened flooding of rice paddies due to the lack or insufficiency of the required volume and / or quality of irrigation water, lack of the necessary technical support for the implementation of all agrotechnical methods necessary for the normal cultivation of rice, reducing the soil reclamation state to a level at which the introduction of organic and mineral fertilizers does not compensate for the low soil fertility and is ineffective and economically inexpedient [13-16]. Long-term practice of rice cultivation on rice irrigation systems of the Krasnodar Territory revealed the urgent problem of a high degree of weed infestation in rice paddies, which in turn requires high expenditures of financial and labor resources to obtain planned yields without reducing the reclamation state of soils [19-20]. Considering all of the above, it becomes obvious the relevance of research on optimization of methods of rice cultivation based on drip irrigation under polyethylene and / or mulching perforated film in relation to the conditions of the Krasnodar Territory
