Abstract

In order to comprehensively evaluate the best pressure and sowing depth conditions suitable for oat growth under dry farming, a sowing pressure experimental device was designed. The calculation methods of pressure strength of different types of press wheels were analyzed. The experiment calibrated the corresponding counterweight under different suppression strengths. A three-factor and three-level orthogonal experiment was carried out with pressure strength, sowing depth and press wheel type as factors and oat emergence rate, dry matter accumulation at seedling stage and yield as main evaluation indexes. The results showed that the press wheel type had extremely significant effects on oat emergence rate, stem and leaf dry matter quality, total dry matter quality at seedling stage and yield, and had significant effects on root dry matter at seedling stage. The pressure strength had significant effects on the emergence rate and root dry matter quality of oat at seedling stage, and had extremely significant effects on stem and leaf dry matter quality, total dry matter quality at seedling stage and yield. Sowing depth had significant effects on seedling emergence rate, root dry matter quality, stem and leaf dry matter quality, total dry matter quality, and had extremely significant effects on yield. The optimum sowing conditions of oat are as follows: pressure strength is 50 kPa, sowing depth is 5 cm, and press wheel type is conical combined wheel. The results of this study could provide certain references for the design of oat high-yield mechanical sowing technology, oat seeder and press device.
