育苗的营养面积对番茄幼苗质量的影响是随苗龄增加而越来越明显。营养面积越大,叶面积越大,茎粗增加、花芽发育早,分化数越多,植株体内的全 N、全 C、非还原糖的含量增加。温度对番茄幼苗生长的影响与营养面积大小的关系很大,当营养面积小时,高温不利于育壮苗,植株体内含糖量是低温>中温>高温。不同地温和不同营养面积培育的秧苗,总产量差异不明显,而早期产量影响显著。在试验条件下,番茄育苗以8×8cm 营养面积和15℃(实际有效地积温328℃)为宜,最大叶宽/最大叶长×叶数和花芽级数和与早期产量显著相关。
The effect of nursery nutrition area on tomato seedling quality is more and more obvious with the increase of seedling age. The larger the nutrient area, the larger the leaf area, the larger the stem diameter, the earlier the flower buds developed and the more the number of differentiation. The content of total N, total C and non-reducing sugars in the plant increased. The effect of temperature on the growth of tomato seedlings is closely related to the size of the nutrient area. When the area of nutrition is small, the high temperature is not conducive to the growth of seedlings. The sugar content in the plants is low temperature> medium temperature> high temperature. The seedlings cultivated in different temperate and different nutrient areas had no obvious difference in the total yield, but the early yield had a significant impact. Under the experimental conditions, nursery tomato seedlings with 8 × 8cm nutrient area and 15 ℃ (actual effective temperature 328 ℃) is appropriate, the maximum leaf width / maximum leaf length × leaf number and flower bud series and early yield was significantly correlated.
