研究表明,厚皮甜瓜全生育期可划分为发芽期、幼苗期、营养生长期、结果期,各期有其生长特点并具临界特征。整个生育期中,全株鲜重、千重,根、茎、叶、果各器官的鲜重与干重的增长均呈S形曲线。全株绝对生长量、相对生长量、日增长量均以结果中期最大。25天日龄的单叶面积达最大值,30天净同化率最高。开花后10~20天内果实重量、体积的增长最快。单株地上部、地下部和 T/R用值均随留蔓数增加而增加。结果中期叶面积指数达最大值,随单株留蔓数增加,叶面积指数增加,且提早增加。单株叶面积与子房体积、重量和果实产量高度相关。
Studies have shown that the whole growth period of muskmelon can be divided into germination period, seedling stage, vegetative growth period, the results of the period has its own growth characteristics and with critical features. The whole growth period, the whole plant fresh weight, thousand weight, roots, stems, leaves, fruit organs of fresh weight and dry weight growth showed a S-shaped curve. The absolute growth of the whole plant, relative growth, daily growth are the largest in the medium-term results. The leaf area reached the maximum at 25 days of age with the highest net assimilation rate at 30 days. Within 10 to 20 days after flowering, fruit weight and volume increase fastest. The above-ground part, underground part and T / R value of single plant increased with the increase of Brassica napus. The results showed that the mid-leaf area index reached the maximum, with the number of per plant increased, leaf area index increased and increased earlier. Leaf area per plant and ovary volume, weight and fruit yield are highly correlated.
