115 многолетним исследованиям наиболее эффективным оказался прямой посев озимых зерновых по нулевой технологии. Так же доказано, что при нулевой технологии даже если пашня загрязнена сорняками, ее можно уничтожить гербицидами. ANNOTATION In the south of Kazakhstan, the main crops of grain and fodder crops (about 80%) are propagated on rainfed crops. The area of arable land on rain fed land in the Turkestan region, according to the data of 2020, is 1073.1, including grain - 446.6 thousand hectares. Numerous reforms that have taken place in the villages and global warming have sharply reduced the sown area to 954.9 thousand hectares, including 349.8 thousand hectares of cereals. With the decrease in sown areas, farmers faced another problem - old, worn-out equipment. Scientific experiments were carried out at the Krasnovodopad Breeding Experimental Station to study the main methods of tillage in the cultivation of winter wheat, winter barley and safflower. In practice, 3 variants of the main tillage are tested: this is the traditional technology - plowing with a plow with a layer turnover to a depth of 25...27 cm. The minimum technology is loosening the soil with a ChKU-4 chisel-cultivator to a depth of 14...16 cm and zero technology, i.e. direct sowing without tillage with a SZS-2.1 seeder with a tip. As a result of sowing winter wheat using these three technologies for 5 years, the average yield per hectare was 15.9 centners per hectare using traditional technology, with a minimum of -16.1 centners per hectare, and with zero - 17.2 centners per hectare. According to many years of research, the direct sowing of winter grains using zero technology turned out to be the most effective. It has also been proven that with zero technology, even if the arable land is contaminated with weeds, it can be destroyed with herbicides. жүктеу/скачать 7.12 Mb. Достарыңызбен бөлісу:
