So, how to grow potatoes with seaweed fertilizer? What is the effect after use? The following is a brief introduction to the application method of the best bacterial fertilizer-Gymboree seaweed bacterial fertilizer on potatoes.
Gymboree seaweed microbial fertilizer is imported from Australia. It adopts the latest international microbial engineering technology and technological means. It is separated and purified from marine organisms. It is the latest generation of pure natural, efficient and highly concentrated broad-spectrum liquid microbial fertilizer. It has the ability of efficient microbial nitrogen fixation, phosphorus dissolution, potassium dissolution and soil activation. It has comprehensive nutrients, no toxicity and no pollution.
1. Tuber cultivation. Generally, the germination of potatoes takes about half a month. During this period, it is unnecessary to apply seaweed bacterial fertilizer, but also appropriate use of bacterial fertilizer seed dressing, can improve germination rate and germination quality.
2. Seedling stage. After unearthed, chase golden baby seaweed bacterial fertilizer once, each time the dosage of 0.5 kg per mu, a total of 2~3 times. Also foliar dressing, spraying with 0.5% bacterial fertilizer supernatant, 3~4 times.

The balance of growth and development was achieved by regulating the relationship between growth and development, vegetative growth and reproductive growth, aboveground growth and underground growth.
4. Tuber swelling stage. This is the critical period for the application of seaweed bacterial fertilizer. Should be timely topdressing watering, keep the soil dry and wet, at the same time, Gymboree seaweed microbial fertilizer diluted by water in the proportion of 1:200 after washing with water.

Cultivation of Potato seedlings in Nutrition Bowl in greenhouse in early Spring
Under the long-term traditional cultivation mode, the phenomenon of high yield and low efficiency of potato is prominent. Therefore, in recent years, a new method of raising seedlings in nutrition bowl and planting in plastic greenhouse has appeared, and good economic benefits have been obtained. 1. The cultivated varieties should choose the varieties with early maturity, low temperature tolerance and relatively high yield, such as Dongnong 303 potato with stable quality and growth period of about 90 days. two。 Soil preparation and fertilization in the autumn of the year before early spring potato cultivation, 6000 kg of mature farm manure and potassium sulfate were applied per mu in the greenhouse.
