Growth and Physiological Characteristics of Sour Jujube Seedlings in Different Substrate Formulations

چکیده
The raising of container seedlings with light substrates has become an important method seedling raising, without delaying the period. In order to reduce reliance on non-renewable peat and promote reuse organic waste, this study compared growth sour jujube in different substrate formulations (i.e., proportions vermicompost instead peat), using a semi-subterranean placement root control bags, explored application seedlings. results showed that there were significant differences physiological photosynthetic characteristics treated substrates, among which A2 (peat: vermicompost: vermiculite: garden soil = 0.5:0.5:1:1) A3 1:2:1) suitable for raising. height, ground diameter, number secondary branches, length longest branch, total fresh weight, aboveground length, projection area, surface area all significantly greater than those grown other substrates. Especially A3, can replace as nursery seedlings, removing dependence resources, reducing costs, providing more prospects application. conditions follows: porosity 44.0–54.0%, electric conductivity (EC) value 0.2 mS/cm, matter 40.39~54.05 g·kg−1, nitrogen phosphorus 1.67~1.91 g·kg−1 0.95~1.20 respectively, alkali-hydrolyzed 139.75~154.69 mg·kg−1, available 137~224 mg·kg−1.

In this study, transplanting cotton seedlings grown in artificial substrate is considered due to recent increased interest in cotton planting labor saving approaches. The nursery methods used for growing cotton seedlings affect root growth. However, the underlying functional responses of root growth to variations in cotton seedling transplanting methods are poorly understood. We assessed the re...
