Description

A kind of custard squash seed accelerating germination method

Technical field

The present invention relates to vegetable growing field, be specifically related to a kind of custard squash seed accelerating germination method.

Background technology

A lot of vegetable seeds need vernalization, and the general seed that needs vernalization can be divided into two classes: a class is that fruit vegetables seed sprouting is slow, need to urge kind, as tomato, capsicum, eggplant, cucumber; An other class is that summer temp is high, causes germination rate of vegetable seeds low, thus also need to urge kind, as asparagus lettuce, spinach, custard squash, garlic.Different vegetables, vernalization mode difference separately.Hang well method, refrigeration, mix micromicrofarad etc.Different vernalization modes, corresponding different vegetable seeds.Before general vernalization,, first through seed selection, sterilization, seed soaking, finally be only vernalization.Conventional germination accelerating method can improve percentage of seedgermination, shortens germination time, alleviates Field diseases, and seedling seedling is neat, Miao Zhuan.But existing germination accelerating method does not all have to improve the nutrient component of vegetables, further improve the quality of vegetables.
