EFFECT OF AERATED IRRIGATION ON SOIL MICROENVIRONMENT AND COTTON GROWTH PROMOTION

Clay soil results in higher crop yield and quality than sandy soil. However, irrigation causes clay to slump easily, increasing compactness decreasing oxygen content. This study investigated the effects of dry seeding wet emergence on microenvironment cotton growth promotion Xinjiang silt loam fields. The experimental design included three aerated non-aerated treatments. showed that decreased density 0–20 cm layer different degrees, field capacity increased 20-30 did not change among WP2 treatment changed most, 0-10 10-20 were respectively 1.28 g cm-3 1.27 cm-3, 35.23% 35.7%. Under same quota, water content treatments was lower Aerated inhibited horizontal diffusion facilitated downward transport. had highest peak temperature at depths 10 20 cm, numbers bacteria, fungi, actinomycetes, urease, catalase activities, seedling emergence, primary root length, plant height, stem thickness.
