我国北方地区日光温室蔬菜生产过程中,土壤起垄覆膜栽培应用广泛。提出了一种新型起垄覆膜栽培方式——起垄内嵌式基质栽培(Ridge substrate-embedded cultivation,RSC),在此基础上衍生出两种形式的起垄覆膜方式,即土壤嵌槽覆膜(RSC-P)和嵌膜覆膜(RSC-W),并研究了包括土垄覆膜(SR)和基质栽培槽覆膜(PEG)在内的4种起垄覆膜方式对甜椒幼苗生长的影响。试验结果表明:相对于SR,RSC-P、RSC-W和PEG 3种起垄覆膜方式能够显著提高甜椒幼苗的株高、叶片数和叶绿素含量,其中株高分别比SR栽培垄的甜椒幼苗高26%、27.5%和32%,叶片比SR甜椒幼苗多4片,叶绿素含量更是显著高于SR栽培的甜椒幼苗。试验表明,设置的3种起垄覆膜方式都能显著促进甜椒幼苗生长。
In the process of vegetable production in solar greenhouse in the northern part of our country, soil ridge coating is widely used. In this paper, a new Ridge substrate-embedded cultivation (RSC) is proposed, which is based on which two forms of Ridge Substrate Coating (RSC-P) and inlaid film (RSC-W) were studied. The effects of four ridge coating methods including ridge soil film (SR) and substrate cultivation groove film (PEG) Effect of pepper seedling growth. The results showed that compared with SR, RSC-P, RSC-W and PEG 3, the ridge-coating method could significantly increase the plant height, leaf number and chlorophyll content of sweet pepper seedlings, The pepper seedlings were 26%, 27.5% and 32% higher than the SR pepper seedlings and the content of chlorophyll was significantly higher than that of the SR pepper seedlings. Experiments show that the three kinds of ridge coating set can significantly promote the growth of sweet pepper seedlings.
