TABLE 1 cabbage Water-saving irrigation test design

Fig. 2 is a diagram of the growth state of cabbage provided by the present invention. FIG. 3 is a graph showing the effect of cabbage yield, fruit diameter and water use under different conditions, and the results are as follows:

through the experimental study of analyzing the influence of the fruit diameter, the yield and the water utilization efficiency of the cabbages under different treatments. As can be seen in fig. 3, there were differences in fruit diameter at harvest under different treatments, but the differences were not very large. With the increase of irrigation quantity, the transpiration evaporation quantity gradually increases, the consumption of soil water is in a trend of reducing, and the yield is in a trend of gradually increasing; when the irrigation amount is increased to a certain value, the irrigation amount is increased, and the increase of the yield is gradually reduced, so that the water utilization efficiency is reduced.

The influence of different treatments on the yield of the cabbages is different, the treatments are obviously different, the highest yield is T6 treatment, the temperature is about 40 ℃ in a test area in 4-9 months, the evaporation capacity is large, the cabbages belong to large leaves, the evaporation of the earth surface can be reduced to a certain extent, and the yield is not obviously increased when the irrigation amount is increased. The water use efficiency gradually decreases with the increase of irrigation amount, and the water use efficiency of the T4 treatment is the highest, namely 184.14kg/m²The yield was lower than that of the T6 treatment, but higher than that of the other treatments, and there was no significant difference between the T4 and T6 treatment yields; according to the maximum benefit principle and the sustainable utilization principle of soil moisture, the T4 is processed into the optimal irrigation quantity and irrigation mode of the cabbages.
