| Abstract: |
| In dry conditions, a two-factor randomized block design was adopted［Factor A is cultivation method, setting two levels of Direct seeding (A1) and Bowl-real transplanting (A2); Factor B is film mulching mode, setting three levels of Full plastic film mulching on double ridges and planting in catchment furrows (B1), Plastic film mulching on ridge and planting in film-side (B2), Flat planting of full ground plastic film mulching (B3)］ to study the effects of different cultivation modes on hot pepper yield, soil moisture content and soil temperature in dry land. The results showed that, compared with A1, the pepper flowering date in A2 was 16 d earlier, red fruit harvest date was 11 d earlier, while the fresh red pepper yield was 13.51% higher, and the total fresh pepper yield was 4.43% higher. The total fresh pepper yield and red pepper yield in B1+A2 were the highest, while the yield of fresh green pepper in B1+A2 was the highest. B1 and B2 can effectively collect rainwater; B3 had the best effect in keeping moisture, and B1 followed. Before fruit setting, with the weather warming, soil temperature rose, different plastic film mulching modes had different effect on soil temperature, B2 was the fastest for increasing soil temper
ature, but was the last for maitaining temperature, while B1 had the best effect on maitaining temperature. In the red fruit harvest, as the ground was covered by plants, the soil temperature decreased, the soil temperature in different mulching modes got similar. Therefore, adoption of B1 ccould obtain the best effect of rainfall-collection and soil moisture preservation, as well as heat preserv
ation. B1+A2 also had best effect in plant height, plant width, number of fruit per plant and total red fruit, red pepper yield and total fresh pepper yield, so as the economic benefit. So it is recommended in hot pepper cultivation in dry land. |
