Cucumber pollution-free fertilization technology

Cucumber is fertile but not fat, and has a lot of nutrient requirements. The roots of cucumber are weak, the roots are shallow, the cork is early, the regeneration is poor, the absorption of soil nutrients is weak, and the soil solution environment can not be tolerated. Otherwise, it is easy to burn roots, burn seedlings, cucumber seedlings have the weakest fertility, and are very sensitive to the concentration of fertilizers, and must be applied lightly.
Cucumber has the characteristic of selective absorption. It is similar to nitrate nitrogen. When only ammonium nitrogen is supplied, the leaf color becomes thicker, the leaves become smaller, and the growth is slow. Cucumber had the highest nitrogen uptake 30 days after planting, with the most uptake of leaves. After 50 days of planting, the leaves and fruits absorbed approximately the same nutrients, and most of the nutrients were absorbed by the fruit for 70 days.
The production of 1000 kg of cucumber requires about 2.5 kg of nitrogen, 1 kg of phosphorus and 4 kg of potassium.
Before planting, the farmer's fertilizer is 4000 kg (or commercial organic fertilizer 1500 kg) and ternary compound fertilizer 50 kg is used as the base fertilizer. When the cucumber enters the early stage of the melon, the first top dressing is carried out. Afterwards, the growth and harvesting conditions are followed by the fertilizer every 7 days to 10 days, and the ternary compound fertilizer or nitrogen fertilizer of 5 kg is gradually increased to 15 kg.
The seed dressing can be applied by foliar fertilizer, and the liquid fertilizer can be used for rooting treatment in the growing season.

Serological Pipette

Disposable serological pipettes with polyester fiber plugs are ideal for tissue culture applications. Crisp, black, highly legible permanent graduations prevent ambiguity and guarantee precise reading and accurate dispensing within ± 2%. Reverse graduations show volume removed or remaining on all pipettes larger than 1mL. Generous negative graduations provide additional pipetting volume. Yongyue's serological pipettes are made from transparent USP Class VI polystyrene sterilized by gamma irradiation. Each lot is free from pyrogens, DNases, and RNases.Yongyue's plastic serological pipettes are produced under the strictest protocols and offer the highest degree of accuracy.
The pipettes are supplied with an aerosol barrier plug that prevents both liquid and aerosols from contaminating the pipettors.
The serological pipettes are produced from crystal clear polystyrene (PS) and are color coded for easy volume identification. Available in 1mL, 2mL, 5mL, 10mL, 25mL and 50mL sizes.
In addition each Pipette now features:
Crisp and bold easy-to-read graduation marks
Reverse graduations on all volumes
Negative graduations on all volumes
1, 2 and 5mL pipettes feature one-piece construction

10, 25 and 50mL pipettes feature three-piece construction
