1、Why are there many plant diseases and pests and poor quality?What should I do?
The main factor of plant diseases and pests and poor quality is low soil organic matter.To change the current situation,it is necessary to increase soil organic matter.The fastest way to increase soil organic matter is to supplement organic fertilizer.The organic fertilizer has a complete nutrient content,which can supplement the nutrition needed by crops and improve the soil quality.However,the organic fertilizer is large in volume,difficult to transport,difficult to decompose,high in labor cost and high in relative cost.based on this,scientists have developed an organic fertilizer-ten kilograms of farm manure with a maximum of five tons,which is called"Shendu"organic fertilizer!
2、Principle of deep crossing
Shendu contains mineral source fulvic acid,organic matter,large and medium-sized microelements and other nutrients required by crops.It has been widely used in a large number of agricultural crops and has been praised for its deep development of crop potential and activation of its own advantages.
3、Advantages of Shendu
1.Non toxic,harmless and no residue:Shendu raw materials are from natural plants,which are non-toxic,harmful,polluting and residual,in line with the direction of national development and promotion of green agricultural fertilizers and pesticides,and provide guarantee for human to enjoy safe,green and high-quality food;It is the first choice for the production of pollution-free fruits and vegetables and organic fruits and vegetables to eliminate crop fertilizer damage,drug damage,herbicide damage and heavy metal damage.
2.Improve the soil and root explosively:adjust the activation,soft soil,balance the pH,prevent soil acidification and hardening,and strongly resist continuous cropping;Improve the root system activity,vigorously root and strengthen the root,raise and protect the root,and make the stem strong and strong.
3.Enhance disease resistance and stress resistance of crops,increase production and improve quality:activate dormant genes of crops,increase disease resistance and insect resistance of crops,and prevent rotten roots,gums,yellow leaves,dead seedlings and dead fruits;Promote flower bud,improve fruit setting rate,prevent fruit falling and cracking,promote fruit expansion and beauty,and taste pure;Timely meet the needs of crop growth,reasonably adjust the effective supply of nutrients in the soil,increase production by 15-60%,reduce the amount of large fertilizer by about 15-30%,and achieve long-lasting fertility.
