title: [Effects of soil surface mulching on the growth and physiological characteristics of grafted and non-grafted cucumbers in solar greenhouse].
abstract: This paper studied the effects of wheat straw mulching, plastic film mulching, and wheat straw plus plastic film mulching on the growth and physiological characteristics of grafted and non-grafted Cucumis sativus in solar greenhouse. The results showed that compared with the control, the plant height, stem diameter, photosynthetic rate, and root vitality of grafted C. sativus under wheat straw plus plastic film mulching, plastic film mulching, and wheat straw mulching were increased by 91, 71 and 57 cm, 0.127, 0.086 and 0.111 cm, 2.63, 2.08 and 1.36 micromol x m(-2) x s(-1), and 0.98, 0.48 and 0.8 mg TTC x g(-1) FW, respectively, while non-grafted C. sativus had a less increment. The chlorophyll content of grafted C. sativus under wheat straw plus plastic film mulching and wheat straw mulching was 1.8% and 3.15% higher than the control, respectively, but that under plastic film mulching was 3.8% less than the control. Soil surface mulching increased the dry weight per plant, early yield, and total yield. Under wheat straw plus plastic film mulching, plastic film mulching, and wheat straw mulching, the individual yield of grafted C. sativus was 16%, 5.3% and 3.4% higher than that of non-grafted C. sativus, respectively.
