摘要

采用大田试验

对春小麦种植、树苗移栽和树木育苗实施了不同土壤保水剂(LT—200

LT—100

博亚和皇冠)处理

研究了不同土壤保水剂应用效果及对植物生长的影响。结果表明

施用土壤保水剂能显著提高春小麦产量和水分利用效率。LT—200

LT—100

博亚和皇冠的产量分别较对照(不施加土壤保水剂)增加13.60%

11.43%

4.13%和3.52%。水分利用效率分别较对照提高1.00

0.84

0.31和0.26 kg/(mm·hm

)。在春小麦收获期

表土层(0—30 cm)土壤容重较对照下降

其中LT—200和LT—100最明显

分别较对照降低9.4%和10.1%。土壤保水剂可以提高土壤贮水量

在春小麦开花期

LT—200

LT—100

博亚和皇冠0—120 cm土层中的土壤贮水量分别较对照提高27.64

26.92

14.04和13.82 mm。施用土壤保水剂对春小麦根干重、旗叶干重及其含水量产生-定的影响

但规律不明显。施用土壤保水剂对树苗移栽和树木育苗也产生-定的影响。

Abstract

Soil water-holding agent is a kind of material for water saving developed in recent years.The agents of LT 200

LT-100(made in San-yan Ind ust rial Company

Japan)

Huang-guan and Bo-ya were tested in field experiments to study the effects of different soil water-holding agents on spring wheat plant

tree transplant

and tree seeding raising.Results showed that in the experiment of spring whea t plant

LT- 200

LT-100

H uangguan and Boya increased yields by 13.60%

11.43%

4.13%and 3.52%

respectively

with the average of 8.17%.They increased water use eff iciency by 1.00

0.84

0.31 and 0.26 kg/ mm ? hm2

respectively

compared with controls(field without adding soil water-holding agents).Especially

the increases by adding LT-200 and LT 100 agents were significant. At same time

LT-200

LT- 100

Huangguan and Boya enhanced soil water storage in 120 cm depth by 27.64

26.92

14.04 and 13.82 mm

respectively

compared with cont rols in spring wheat planting experiment.Soil water-holding agents couldincrease the dry root weight of spring wheat

but the increases were insignificant.Effects of different soil water-holding agents on tree transplant and tree seeding raising in one year growth were limited.Applied methods and the amount of soil water-holding agents added to soil need further studies.
