الوصف: | Quality researches have been made, while preparing stubble for sowing in different variants. Straw were gathered while harvesting in following variants: unchopped, spread on soil surface; chopped and spread; and unchopped, raked and taken out. Stubble soil was loosen by heavy cultivator wrought coulter, plates, stubble cultivator flat-cutting coulter, tilled or absolutely not tilled. It was sown by disc and hoe coulter drill. Barley and winter wheat were grown. Researches were made in 2002-2003. While treshing, the fraction consist of chopped straws was evaluated, as well as the influence of plant kind upon chopping. The amount of sttraws inserted in sowing noth by disc an hoe coulter was investigated due to straws gathering variant and it's amount. It was established the influence of chopped straws upon soil fraction consist in sowing notch, the soil straws cover, crop viability, amount of weeds, harvest. It was established that chopped straws reduce the amount of small-scale soil fractions (<2 mm), and increase the large-scale (>10 mm) ones. After sowing the largest soil straw cover in investigated variants remain, when they are spread and sown in unloosen stubble, the smallest - when they are raked and soil is tilled by heavy cultivator. Using the latter variant, crop viability is the best. Though there is a great influence of common agro-technical requirements existence and climate conditions upon crop viability. The amount of short-lived weeds in crop is influenced by intensity of stubble soil loosen. The smallest amount of weeds is when sowing in untilled stubble, the biggest - in ploughed one. The smallest grain harvest was received after raking straws and sowing into unloosen stubble. When sowing into unloosen stubble, covered by chopped straws, it was noticed ther harvest reduce in margin of error. |
