The Study Of Different Root-Soil Space On Vegetables Growth Contribution Rate Of The Cabbage And Cucumber

The test material for cabbage and cucumbers, The interlayer limits use nylon net and plastic cloth, Each interlayer limits set up four levels (interlayer were laid under the surface soil10cm、20cm、30cm、40cm from0-10cm、0-20cm、0-30cm、0-40cm four differently kinds of root-soil space)。Analysis the effect of root-soil space on growth indexs、yield、 yield contribution rate of cabbage and cucumber of solar greenhouse.And the effect of root-soil space on cucumber physiological index、levels maximum daily water consumption in furit period and quality. The effect of different water treatment on cucumber yield and yield contribution rate of plastic cloth interlayer limits。The main results were as follows.The effect of nylon net interlayer restrict treatment on the contribution rate of cabbage growth.it is concluded that,compared with the control, the effect of nylon net interlayer treatment on cabbage average leaf number, average plant height, average diameter, average leaf show is no significant.The effect of different treatment on cabbage yield abtain that compared with the control,10cm root-soil space is significant difference with control, other treatments is no significant difference with control。The treatment of W10、W20、W30、W40yield contribution rate respectively reach to82.13%、91.18%、94.84%、99.89%of control。Therefore, we concluded that the yiled of cabbage increased with the increase of root-soil space under the treatment of nylon net interlayer restrict。The effect of plastic colth interlayer restrict treatment on cabbage growth, the result show that the effect that different treatment on average leaf number, average plant height, average diameter, average leaf show of cabbage is no significant. Different treatments on dry matter quality and yiled of cabbage, compared with the control, the treatments of S10is difference significant with control, others treatment is no difference significant with control.The yiled contribution rate of different treatment of S10、S20、S30、S40respectively reach to82.97%、87.25%、100.13%、101.05%of control.The effect of nylon net interlayer restrict treatment on the growth of cucumber, Compared with the control, the effect of different treatment on cucumber growth index、 physiological index and yield is no significant with control, and the impact on the quality of different nylon net interlayer treatment also did not reach significant difference; All nylon net interlayer restrict treatment yield contribuition rate reach to101.95%.103.49%.102.21%、102.12%of control, the yield contribution rate of nylon net interlayer treatment were greater than101.00%, At the same time, it is show that the nylon net interlayer root restrict did not reduce the yield of cucumber,10cm vertical root-soil space can achieve the output which had no significant difference with the control.The effect of plastic cloth interlayer restrict treatment on the growth of cucumber, compared with the control, the effect of plastic cloth interlayer restrict treatment on average leaf number、average plant height、average diameter of cucumber is no significant.The yield contribution rate of treatment S10. S20. S30. S40can reach to88.07%、96.41%、96.99%、98.06%of the control. Compared with the control, the yield of S10treatment is significant difference with control, other treatment is no significant difference with control。The yiled of different treatment which root interlayer restrict with plastic cloth show a certain regularity, along with the increase root-soil space, the output increase。The effect of root-soil space interlayer restrict on consumption of cucumber in fruit period, we obtain that under two kinds of root-soil space interlayer restrict pattern, the daily maximum water consumption amount of all treatments show that full fruit period>late fruit perid>early fruit period。It is suggested there is less impact between the pattern of interlayer restrict and the daily maximum water consumption。It is the same interlayer restric pattern concerned that the effect of nylon net interlayer on the daily maximum water consumption amount of different treatment is lesser; The effect of plastic cloth interlayer on the daily maximum with the increase of root-soil space, water consumption has a tendency to increase。Combination of two kinds of root interlayer on the contribution rate of vegetable growth, we obtain that cucumber at least20cm root-soil space can reach the yiled which is no significant with control.The cabbage need30cm root-soil space can meet the growth development and yield formation.
