Because garland chrysanthemum has the characteristics of low temperature resistance, coolness, light tolerance, low light saturation point, and low photosynthetic intensity, it is not only feasible to use garland chrysanthemum in the greenhouse in autumn and winter seasons, but also can be listed during the Spring Festival, greatly improving the economy. benefit. The cultivation points are as follows: First, the time in the northern region in the early October to mid-November, listed during the Spring Festival. Second, seed selection should use strong cold resistance, comparative disease resistance, good quality and high yield varieties. Third, sowing and sowing when the removal of the greenhouse before the stubble residue, soil preparation, Mushi farmyard fertilizer 3000-4000 kg, turning the ground 15-20 cm deep, semi-high sorghum, is conducive to increase the soil temperature, the width of 1-1.2 meters The width of the surface is 0.8-1m, the height of the beak is 8-10cm, the amplitude of the broadcast is 7-8cm, and the cover soil is 1.5cm after sowing. The sowing rate of the mu is 2500-3000g, and the seedling emergence is 6-7 days after sowing. Fourth, after the emergence of management to strengthen management, the early temperature is relatively high, late low temperature, temperature control at 17 °C -20 °C, more than 28 °C vent. Detrimental to the growth of more than 30 °C, at this time, photosynthesis decreased or stopped, growth was affected, thin leaves, increased fiber quality is not good. The minimum temperature should be controlled above 12°C to avoid freezing or freezing. Since it is in the cold season, it is generally not watered, promotes deep rooting, and has high humidity and low temperature, and is prone to damping-off. When growing 8-10 leaves, choose the first time of sunny and warm water, combined with water to chase after a fertilizer, Mu chase ammonium sulfate 15-20 kg. During the growing period, it is watered 2-3 times and watered in sunny and warm weather in the morning. The amount of water should not be too large and the humidity should be controlled below 95%. If the humidity is high, you should choose to exhale at high temperatures at noon on sunny days to prevent the occurrence of diseases. Artemisia selengensis grows in the greenhouse. Due to weak light, low temperature and high humidity, it is prone to damping-off, leaf blight and downy mildew.
Polyglutamic
acid is a natural occurring, multi-functional, and biodegradable biopolymer. It
is produced through fermentation by Bacillus subtilis using glutamic acid. PGA
is consists of glutamic acid monomers cross-linked between α-amino and
γ-carboxyl groups, and the molecular weight of PGA is usually between 100~1000
kDa. It is water-soluble, edible and non-toxictowards human, and is environment
friendly. It has broad applications in the fields of medicine, food, cosmetics,
and water treatment.
Applications
*Base Fertilizer:
Use
it about 10kgs for a unit of area, then irrigate with clean water or muck
water. Or irrigate amino acid together with water. Or fertilize with other
compound fertilizers, broadcast application, hole application both are ok. It
is applicable to all the crops.
*Foliar Fertilizer:
Dilute
it by 800-1000 times and spray directly. Also, it can spray by mixed with trace
element. Use 200-500g for a unit of area.
*Compound Fertilizer &
Irrigation Fertilizer:
It
can be added to compound fertilizer by rate of 5-8%, improve the nutrient
content of compound fertilizer, increases crops` direct absorption.
Advantage For Fertilizer Gamma-PGA
1.Easy
and high-efficacy absorption by plants.
2.Help
the absorption and the translocation of the nutrients in cells.
3.Improves
the immune system of the crops and increases their resistance against diseases,
severe weather.
4.Simulates
protein synthesis and gives strength to plants accelerating their growth
