First, the requirements of the soil conditions. The requirement of peas for soil quality is not strict, but it is appropriate to use a loam or clay soil with a pH of 6.0-7.2. Below pH 5.5, it is prone to disease and reduced scarring. Since pea root exudates affect the rhizobia activity and root growth of the following year, peas must not be contiguous. Second, the need for fertilizer characteristics. During the vegetative growth stage of peas, the growth was small and nutrient absorption was also low. After flowering and sitting, the growth amount increased rapidly, and the nutrient uptake also increased significantly. The peas absorbed nitrogen, phosphorus and potassium in their lifetime. The most common, followed by potassium, phosphorus is the least. Although the root nodule of pea can fix soil and nitrogen in the air, it still needs to rely on soil nitrogen supply or nitrogen fertilizer supplementation. The nitrogen supply status of root nodules is often considered in the application of nitrogenous fertilizer. In the early stage of fertilization, if nitrogen is applied too much, the nodule formation will be delayed and the stems and leaves will grow too luxuriantly to cause flower failure; if nitrogen is insufficient during the harvest period, the harvest period Shorten the output and reduce it. The application of phosphorus and potassium fertilizers can promote the formation of pea root nodules, prevent leggy and enhance disease resistance. Third, fertilization techniques 1, basal: pea roots early and rapid development, 6 days after sowing seedlings not yet unearthed, the main root will be extended 6-8 cm, 10 days after sowing seedlings just unearthed, there are more than 10 thick roots The main root can be as long as 16 centimeters when two compound leaves have just started in 20 days. Therefore, basal fertilizers should put special emphasis on early application. The spring sowing in the north should apply basal fertilization in the autumn cultivation, while the autumn sowing in the south should also apply basal fertilization before sowing, so as to ensure the seedlings are full and the seedlings are strong. Generally, 3000-5000 kg of organic fertilizer, 25-30 kg of superphosphate, 10 kg of urea, 15-20 kg of potassium chloride, and 100 kg of plant ash are applied per acre. 2, top dressing: According to the growth of peas, the first time in the beginning of flowering can be top dressing, generally apply 5 kg of urea, 5 kg of potassium chloride or 15-20 kg of ternary compound fertilizer, combined with watering; After sitting on the urn, 7.5 kg of urea, 7.5 kg of potassium chloride or 20-25 kg of ternary compound fertilizer are collected per mu, and watering is combined.
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
