Optimal planting pattern of cotton is regulated by irrigation amount under mulch drip irrigation.

ABSTRACT:

Objective

It is of great importance to explore agronomic management measures for water conservation and cotton yield in arid areas.

Methods

A four-year field experiment was conducted to evaluate cotton yield and soil water consumption under four row spacing configurations (high/low density with 66+10 cm wide, narrow row spacing, RS_66+10H and RS_66+10L; high/low density with 76 cm equal row spacing, RS₇₆H and RS₇₆L) and two irrigation amounts (CI:conventional drip irrigation; LI:limited drip irrigation) during the growing seasons in Shihezi, Xinjiang.

Results

A quadratic relationship was observed between the maximum LAI (LAI_max) and seed yield. Canopy apparent transpiration rate(CAT), daily water consumption intensi
