摘要 | [目的]研究不同覆盖措施对农田土壤水、热、盐及大豆产量的影响,为促进陕北安塞县山地梯田
作物增产提供理论基础。[方法]以大豆(中黄 35 )为试验材料,设置地膜覆盖( M )、谷子秸秆覆盖量
5 000kg / hm
2 (
J 5
)与 2 500kg
/ hm
2 (
J 2 )和传统耕作( CK ) 4 个处理进行了系统对比试验 。[结果] ① 除
20 — 40cm 土层的结荚期外,其他土层各时期 M 和 J 5 处理的土壤贮水量均高于 CK 处理。另外在 0 — 60
cm 各土层中,出苗期 M 处理的土壤贮水量均高于 J 5 处理; ② 在 0 — 60cm 各土层中,全生育期 M 的土壤
温度均高于 CK 处理,除结荚期外, J
5 处理的土壤温度均低于 CK 处理; ③ 在一定范围内, M 处理可提高土
壤电导率,且在 0 — 20cm 土层中, M 和 CK 处理的电导率差异达到极显著水平(
p <0.01 ); ④M 和 J 5 处理
的大豆产量分别显著高于 CK 处理 46.73% (
p <0.01 )和 34.61% ( p <0.05 ); ⑤ 在一定范围内,大豆产量
与其全生育期的平均土壤贮水量、土壤温度和土壤电导率呈正相关关系。且相较于其他生长阶段,出苗期
土壤物理条件对大豆产量的影响更为明显。[结论]大豆产量与出苗期土壤贮水量和电导率极显著正相
关,且地膜覆盖有利于提高出苗期土壤贮水量和电导率,可促进大豆增产。 |
其他摘要 | [ Objective ] We studied the effects of different mulching measures on the soil water , heat , salt , and
soybean yield in the farmland , in order to provide a reference for promoting crop yield in the mountain
terraces of Ansai County , Shaanxi Province. [ Methods ] The soybean (
Zhonghuang 35 ) was used as the
material where this experiment included four treatments : film mulching ( M ), mulching with 5 000kg / hm
2
straw ( J 5 ), mulching with 2 500kg / hm
2
straw ( J 2 ) and traditional tillage ( CK ) . [ Results ] ① The soil water
storage of M and J 5 treatments during growth stages were higher than that of CK treatment , except for the
podding stage in the 20 — 40cm soil layer.Additionally
, the soil water storage of M in the seeding
stage was
higher than the J 5 treatment in each soil layer.②In each 0 — 60cm soil layer , the soil temperature of M was
higher than the CK treatment , during the entire growth stage.The soil temperature of J 5 was lower than the
CK treatment , except during the podding stage.③ M treatment can improve soil conductivity in a certain
extent.The conductivity has a significant difference between M and CK treatments (
p <0.01 ) in the 0 — 20cm soillayer.④ The soybean yield of M and J 5 were significantly higher than that of the CK treatment ,
by
46.73%
(
p <0.01 ) and 34.61% ( p <0.05 ), respectively.⑤ There was a positive correlation between soybean yield
and average soil water storage , soil temperature , and soil conductivity , during the entire growth period in a
certain extent.Compared with other growth stages , the physical soil conditions had a significant effect on
soybean yield during the seedling stage. [
Conclusion ] There is a significant positive correlation between
soybean yield and soil water storage and conductivity , during the seedling stage.Therefore , film mulching
can improve soil water storage and electrical conductivity during the seedling
stage and promote soybean yield. |
