精品无机小青瓜

 
小黄瓜种子价钱较贵,育苗时采用精量收获,可运用穴盘或养分钵等。荷兰小黄瓜对温度要求很高,发芽适温为24——26℃,温度高,发芽快,但胚芽细长;温度低,出芽慢,甚而烂种。普通4天出苗。出苗后,白昼坚持23——25℃,夜间16——18℃。黄瓜苗的根系喜湿怕涝,喜温怕冷,有氧呼吸旺盛。因而,一定要选用通气良好、保温、保肥、渗水、保水才能强的基质,如草炭、蛭石、珍珠岩、可可泥炭等。
定植
 
1.整地、作畦、施基肥 小黄瓜具有丰产性的特点,它有较大的叶片,异化面积大,结瓜期早,可延续结瓜,但这些特点与根系吸收能力较弱相矛盾,因而在定植前要精密整地,少量施用有机肥,普通667平方米施腐熟禽畜粪肥5000kg以上,再补施些复合肥。做成小高畦,畦宽1一1.2m。
 
2.定植 定植规范为2一4片真叶,苗龄25天左右。定植密度为2500株/667平方米。定植后立刻浇稳苗水,使幼苗土地与畦土亲密结合,利于根系向四周开展。

Cucumber seeds are more expensive, and they are harvested with precision during nursery, and they can be used in trays or nutrient bowls. The Dutch cucumber has a very high temperature requirement. The suitable temperature for germination is 24-26 ° C. The temperature is high and the germination is fast, but the embryo is elongated; Normally emerge in 4 days. After emergence, adhere to 23-25 ​​° C in the day and 16-18 ° C at night. The root system of cucumber seedlings likes to be wet and afraid of waterlogging, like temperature and cold, and has aerobic respiration. Therefore, we must choose a substrate with good ventilation, heat preservation, fertilizer retention, water penetration, and water retention, such as peat, vermiculite, perlite, and cocoa peat.
Colonization
 
1. Soil preparation, cropping, and fertilizing cucumbers have the characteristics of high yield. It has large leaves, large alienation area, early fruit formation period, and can continue fruit formation. However, these characteristics contradict the weak absorption capacity of the root system. Precise land preparation is required before planting, a small amount of organic fertilizer is applied, common manure of 667 square meters is over 5000kg, and then some compound fertilizer is applied. It is made into a small high border, with a border width of 1.1-1.2m.
 
2. Planting The planting specification is 2 to 4 true leaves, about 25 days old. The planting density is 2500 plants / 667 square meters. Immediately after planting, water the seedlings to stabilize the seedling soil and border soil, which is beneficial to the root system to spread around.
