Keyword磁化水 甜菜 土壤盐分 产量 品质 Magnetized Water Sugar Beet Soil Salinity Yield Quality

论文研究不同强度磁化水对土壤、 甜菜产量及品质的影响。 文中通过土柱入渗试验、 室内种子萌发试验和大田丰产技术试验的综合分析, 最终探索出适宜于轻中度盐渍化耕地的最佳磁场强度。 得出以下主要结论:(1)磁化处理有效地提高土壤下渗的湿润锋和加速对土壤盐分的淋洗作用,1600+2400 Gs 处理的湿润锋值最大, 为 28.8 cm, 较 CK 处理提高 30.9%, 入渗结束所用时间为 2.65 h, 较 CK 处理提高 16.4%。 在积盐层, EC 值达到最大,1600+2400 Gs 处理达到 29.33 mS·cm-1, 较 CK 处理提高了 78.5%。(2) 磁化处理可有效的提高土壤含水量, 可显著降低土壤含盐率, 加速土壤中的养分溶解, 促进甜菜植株对其的吸收利用, 二次磁化高于一次磁化, 以1600+2400 Gs 最佳。 在甜菜生长发育的三个时期, 1600+2400 Gs 处理的土壤含水量较 CK 提高 18.2~23.1%。 1600+2400 Gs 处理有机质的溶解率为 7.4%, 碱解氮、 有效磷和速效钾溶解率分别为 21.8%、 14.6%和 5.6%。(3) 磁化水可显著促进甜菜种子的萌发, 甜菜的产量的构成要素及品质均有不同程度的提升, 均以 1600+2400 Gs 处理效果最佳。 1600+2400 Gs 处理的产量为 107100 kg·hm-2, 提高了 36.9%; 产糖量为 14400 kg·hm-2, 提高了 39.1%。可 溶 性 糖 提 高 了 1.1~3.7% , 蛋 白 质 提 高 了 31.9~105.6% 和 氨 基 酸 提 高 了10.8~45.4%。(4) 在土壤盐渍化轻中度(以硫酸盐为主) 的试验区, 磁化水可有效提升甜菜的产量和品质, 及对土壤中盐分的淋洗, 二次磁化效果较为显著, 以1600+2400 Gs 处理效果最佳。

Other Abstract

The effects of magnetized water with different intensities on Yield and quality ofsoil and beet were studied in this paper. Through the comprehensive analysis of soilcolumn infiltration test, indoor seed germination test and field high yield test, theoptimum magnetic field strength suitable for light and moderate salinized cultivatedland is finally explored.The main conclusions are as follows:(1) Magnetization treatment effectively improve soil wetting front of infiltrationand accelerating leaching of soil salt, the wetting front of 1600+2400 Gs processing isbest, the value is 28.8 cm, increased by 30.9%, compared with the control groups.Infiltration used over time to 2.65 h, increased by 16.4%, compared with the controlgroups. In the salt deposit layer, the EC value reached the maximum, with the besttreatment at 1600+2400 Gs, reaching 29.33 mS·cm-1, and 78.5% higher than CKtreatment.(2) The magnetization treatment can effectively improve the soil moisturecontent, can significantly reduce the soil salt content, accelerate the dissolvednutrients in the soil, and promote the absorption of sugar beet plant for its use.Secondary magnetized above a magnetized, 1600+2400 Gs is best. In the threeperiods of growth and development of beet, the soil moisture content of 1600+2400Gs was 18.2 to 23.1% higher than CK. The dissolution rate of organic matter,alkali-soluble nitrogen, effective phosphorus and instant potassium in soil was 7.4%,21.8%, 14.6% and 5.6%, respectively.(3) The magnetized water can significantly promote the germination of beetseeds, and effectively promote the number of crops, single plant weight, yield, sugaryield and quality of beet, which are best treated with 1600+2400 Gs. The yield of1600+2400 Gs was 107,100 kg·hm-2, which was 36.9% higher than CK. The yield ofsugar was 14400 kg·hm-2, which was 39.1% higher than CK. The soluble sugar,protein and amino acid content of the beetroot tuber were increased by 1.1 to 3.7%,31.9 to 105.6%, 10.8 to 45.4%, respectively.(4) In the experimental area of soil salinization, mild-to-moderate (mainly sulfate), magnetized water can effectively improve the yield and quality of sugar beet,and leaching of soil salt, secondary magnetized effect is significant, with a 1600+2400Gs processing effect is best.
