辣椒是冬季育苗的重要内容,其育苗难度仅次于茄子种子。北京地区多数的育苗方式是浸种→湿润床高温催芽→露白后播种。由于育苗过程中难以将水分与温度调控至最适状态,而造成出苗不整齐、出苗率低、苗弱。除此之外,辣椒种子露白后,胚根脆弱,若拌砂播种会使胚根碰伤或脱落,为此,撒播露白的湿种子,也是个难题。北京郊区旧式的“喷籽”播种,也是不得已的做法。为改变原有的育苗方式,现将徐本美研制的辣椒催芽剂的应用效果报导如下。
Pepper is an important part of winter nursery, its nursery difficulty second only to eggplant seeds. Most of the nursery in Beijing is the soaking seed → wet bed germination → dew white after sowing. As the process of raising seedlings is difficult to regulate the water and temperature to the most appropriate state, resulting in irregular emergence, emergence rate is low, weak. In addition, the pepper seed dew white, the radicle fragile, if the mixed sand planting radicle injury or fall off, therefore, sow the wet white seeds, but also a problem. The old-style “seed-spraying” sowing on the outskirts of Beijing is also a last resort. In order to change the original seedling breeding methods, the application effect of pepper germination agent developed by Xu Benmei is reported as follows.
