- 摘要:
- 以春大棚番茄“郑番12158”为试材，研究了定植密度和留果穗数对春大棚番茄生长及产量和品质的影响，以期为番茄生产提供指导。结果表明：留果穗数越多株高越高，留4、5、6穗果对果实中的糖酸含量影响不明显，留果穗数与果实中的酸含量及果实的硬度均无相关性，对果实的品质影响不大。667 m2定植密度6 800株，留2穗果早熟性最好；667 m2定植密度4 100株、留4穗果总产量最高，植株生长和品质综合表现最好。
- Abstract:
- ‘Zhengfan 12158’ tomato was used as experimental material，the effects of different density and spike number on plant growth,yield and quality of tomato were studied in spring greenhouse,in order to provide production guidance of tomato.The results showed that the higher the number of spikelets,the higher the plant height.Retention of 4,5,6 spikelet had little effect on the content of glycolic acid in fruit.There was no correlation between the number of spike and the acid content and hardness of fruit.In addition,the number of spikelets had little effect of fruit quality.The best treatment for prematurity was that planted 6 800 plants per 667 m2 and preserved two panicle fruits.According to the yield,the integrated performance of plant growth and quality,planting 4 100 plants per 667 m2 density and preserving four panicle fruits was the best.
