硼肥和保水剂配施对甜菜硼吸收利用的影响
Effects of Boron Fertilizer and Water Retaining Agent on Boron Absorption and Utilization of Sugar Beet
摘要
Abstract
Using sugar beet variety'Beta 796'and'ST 13092'as test materials,a two-factor experimental design was adopted and four boron application treatments were set up,namely 0(M0),1.2(M1),2.4(M2),and 4.8(M3)kg·hm-2;two water retaining agent treatments,namely 0(Z0),75(Z1)kg·hm-2,and were used to study the effects of boron fertilizer and water retaining agent on boron nutrient absorption and yield in drip-irrigated beets.The results showed that the boron content of beet increased first and then decreased with the increase of boron application,reaching its maximum under M2 treatment.The boron content in different organs of beet follows the order:leaves>petioles>roots,with the M2 treatment resulting in increases of 6.09%to 54.55%in boron content in leaves,7.17%to 49.68%in petioles,and 11.08%to 73.70%in roots compared to other treatments.Compared with the leaf cluster stage,the proportion of boron accumulation in beet leaves and petioles decreases by 8%to 19%and 3%to 7%respectively at harvest,while in the roots increases by 14%to 24%.After application of water retaining agent,the boron content in leaves,petioles and roots of beet increased by 10.56%～32.73%,3.66%～25.04%and 20.11%～57.38%,respectively,compared with the treatment without water retaining agent.Under the same treatment conditions,boron accumulation in leaves,petioles and roots of'Beta796'was increased by 0.45%～15.64%,0.89%～13.72%and 1.15%～15.79%compared with'ST13092'.The apparent utilization of borax fertilizer of'Beta796'and'ST13092'varieties reached the highest in M2 treatment,which were 42.43%and 37.89%,respectively.Therefore,the application of 3.1～3.5 kg·hm-2 borax fertilizer and 75 kg·hm-2 water retaining agent with water drops in the leaf cluster stage can increase yield and efficiency of sugar beet and improve the apparent utilization rate of borax fertilizer,providing case support for the sustainable production and management of sugar beet in Xinjiang.关键词
