During the period of cucumber growing in greenhouses, due to the effects of water, fertilizer, temperature and light, they often show various symptoms that affect yield. Recently, friends of vegetable farmers have reflected the symptoms of cucumber during the fruiting period. We will now summarize and introduce the solutions for reference.
First, the flower hit the top disease that is melon topping, melon vine growth point shrinking, dark green leaves, young melons rise above the growing point, reproductive growth and vegetative growth at the same time by obstacles. This type of vine is caused by excessive fertilization (especially nitrogen fertilizer) or excessive spraying of pesticides. Management should take three measures: First, re-cast a water, with the water applied a small amount of human urine excretion; the second is to spray a low concentration of gibberellin at the growth point; three is top dressing, a small number of times.
Second, the melon skin yellowing cucumber in the fruitful period, the leaves are large, fast growth, high yield, but often yellow rind, reducing the value of goods. Melon yellow is caused by nitrogen deficiency and iron deficiency. The measures that should be taken are as follows: First, 5 kg of ferrous sulfate sulphate; Second, spraying multi-element liquid fertilizer (fertilizer containing iron) on foliar to make melon skin Change from yellow to green.
Third, the lack of melon disease pods dark green from top to bottom leaves thick, up to 20 cm in diameter, stem diameter, and a few melons, a section of a melon or a section of a melon, yield greatly reduced. This symptom is caused by too much N fertilizer and insufficient P and K fertilizer. The following measures should be taken: First, no nitrogen fertilizer such as ammonium nitrate, ammonium bicarbonate or urea should be applied or less applied within 20 days; secondly, compound fertilizers such as phosphate fertilizer or diammonium phosphate should be re-applied immediately. After 5 to 10-15 kilograms, the fruit will be full after 10 days.
Fourth, melons, melons and melons are melons but not long, young melons become yellow and soft, rot or fall. Melon causes: First, the application of organic basal fertilizer is low, nitrogen deficiency, malnutrition, mandrill; Second, leaves are susceptible, especially gray mold, photosynthesis weakened; Third, indoor temperature is too high, photosynthesis disorders; Fourth, Root melons and the lower picking are not timely, nutrition can not be redistributed; Fifth, lack of light. In short, it is all due to imbalances in nutrition supply and demand. This disease should be re-applied nitrogen fertilizer. Vanilla vinegar leaves can be quickly spread leaves broad and strong; Shiba ammonium leaves large and thin and yellow can quickly make leaves dark green. Prevent disease early, timely spraying; early cover the cover film, to prevent high temperature and high humidity scars; daytime room temperature control at 24 ~ 28 °C, no more than 30 °C, night control at 14 ~ 18 °C; root melon to Picking early, when the melon flower begins to wilt, it will be picked, which can reduce the melon.
Five, crisp leaf disease, dark green leaves and dry wrinkled, leaf edge drooping, fingering that is broken, small and small melon strips, is the amount of organic base fertilizer is too little, monotonous due to top dressing. Before the planting, chicken manure and cake fertilizer should be applied. Fertilizer, manure and urine should be applied alternately, and foliar fertilizer should be applied.
Sixth, dry leaf disease First, wind disaster, such as before March, the temperature changes in wind power, such as noodles in the vent noodles, wilting, 3 days after the chlorosis and dryness as a wind disaster; 2 is heat damage, after March, the temperature in the shed up to 40 °C, the leaves in the middle and front part of the vine and the leaves in the vicinity of the shed film are easy to dry out; the third is the phytotoxicity, the excessive spraying concentration or the improper use of the medicine can make the vine wilting. The remedy is: No matter what causes the wilting of the leaves, spray the water immediately on the leaf surface, or flush the leaves. Spray the water for 3-5 hours and then spray the leaf surface fertilizer to restore the function of the leaves.
[Composition]
The main component of this preparation is human immunoglobulin, which is prepared by cold ethanol fractionation of human plasma from healthy donors. The manufacturing process contains a step to remove anticomplementary activity and a dual viral inactivation process. It contains a suitable amount of glucose or maltose as stabilizer (see table below), but does not contain any antiseptic or antibiotic. The distribution of IgG subclasses is close to the serum level of normal subjects and maintains the bioactivity of Fc fragment of IgG.
[Indications]
1. Primary
agammaglobulinemia, such as X-linked hypogammaglobulinemia,
common variant immunodeficiency diseases, immunoglobulin G subclass deficiency,
etc.
2. Secondary
immunoglobulin deficiency diseases, such as severe infection, septicemia of
newborn, etc
