Application method and notice of humic acid fertilizer

Humic acid fertilizer is a new type of fertilizer containing humic acid. The main types of humic acid are humic acid, nitro humic acid and purified humic acid products. The former two kinds of humic acid compound fertilizer are mainly used as base fertilizer with nitrogen, phosphorus, potassium and trace elements. Purified humic acid is mainly used to irrigate or spray crops as a growth regulator. At the same time, it can also be used as seed soaking, which can improve the germination rate and cultivate strong seedlings.



 1. Application

(1) Base fertilizer. 0.02% ～ 0.05% humic acid solution mixed with farm manure (300-400 kg / mu), or ditching and digging foundation. Paddy field can be combined with soil preparation and irrigation.

 

(2) topdressing. At seedling stage and heading stage, 250 kg of water solution containing 0.01% - 0.1% humic acid was used to irrigate near the root system (do not touch the root system). The application of sodium humate or potassium humate in rice field can increase seedlings, strengthen ears and promote growth and development.

 

(3) spraying outside the root. From the late flowering stage to the early stage of grain filling, spraying 50-75 kg of water solution containing 0.01% - 0.05% humic acid per mu for two or three times can make the seeds plump, increase the 1000 grain weight and reduce the shrinkage rate. The best spraying time is 2-6 PM.

 

(4) soaking seeds. The seeds were soaked in aqueous solution containing 0.01% - 0.05% humic acid. The seeds of vegetables and wheat were soaked for 5-10 hours, and rice and cotton were soaked for more than 24 hours. It can increase the germination rate, sprout early and enhance the ability of rooting. 5. Dip the seedling roots and cuttings. Before transplanting rice, sweet potato and vegetables, soak the roots with 0.05% - 0.1% sodium humate and potassium humate solution for several hours, or dip the seedling roots and soak the fruit tree cuttings when transplanting. It can increase secondary rooting, shorten slow seedling stage and improve survival rate. A kind of

 

2. Precautions

Humic acid fertilizer as base fertilizer and seed fertilizer is better than topdressing, concentrated application is better than spreading application, deep application is better than shallow application. At the same time, rotten fertilizer can not completely replace inorganic fertilizer and farmyard manure, but must be combined with chemical fertilizer and organic fertilizer, especially with phosphate fertilizer.

 

It is necessary to master the appropriate concentration when applying various kinds of rotten fertilizer because of different input ratio, different manufacturing methods and different nutrient contents.

 

Humic acid potassium and sodium are hormone fertilizers. Attention should be paid to the temperature. After application, the effect is slow in cold days and fast in hot days. Generally, the temperature should be more than 18 hours. If the temperature is higher than 38 ℃, it will accelerate the respiration of crops, reduce the accumulation of dry matter and reduce the yield.

 

Only when the soil moisture is sufficient and irrigation conditions are good, can the fertilizer effect be brought into full play.

The role of gamma-aminobutyric acid in agriculture

图片
  γ-aminobutyric acid (CAS number: 56-12-2), (GABA for short), with a relative molecular weight of 103.1, is a four-carbon, non-protein amino acid, which is widely used in vertebrates, plants and Widespread in microorganisms. The content of GABA in plant tissues is extremely low, usually between 0.3 and 32.5 μmol/g.  It has been reported in the literature that the enrichment of GABA in plants is related to the stress response experienced by the plant. When subjected to stress such as hypoxia, heat shock, cold shock, mechanical damage, and salt stress, it will lead to the rapid accumulation of GABA.  It has become a research hotspot to process plant food raw materials into GABA-rich functional products after a certain stress treatment or through microbial fermentation to increase the GABA content in the body.  As a novel functional factor, GABA has been widely used in the food industry.  Foods developed using raw materials such as GABA-rich  germinated brown rice  , soybeans and broad

Analysis on the role of rhizobia in soybean planting

图片
Rhizobium soybean is a live microbial preparation. The rhizobia in the root nodules and the legumes are mutually beneficial: the organic matter produced by the legumes through photosynthesis is partly supplied to the rhizobia; the ammonia produced by the rhizobia through biological nitrogen fixation is supplied to the legumes plant. , it fixes free nitrogen in the air to supply soybeans to meet soybean demand for nitrogen. It is a good measure to increase soybean yield, save fertilizer and reduce pollution, and has been valued by researchers around the world. First, the role of rhizobia 1. Nitrogen fixation Soybean rhizobia uses the products of soybean photosynthesis as energy, and converts nitrogen in the air into nutrients required for soybean growth and development. Rhizobium and soybean have a symbiotic nitrogen fixation relationship. At the beginning, soybean rhizobia fixed little nitrogen, until flowering to drum. The initial stage of grain is the peak of nitrogen fixation by so

The new cotton shoot-controlling product--prohexadione calcium, which is better than uniconazole, does not cause premature aging!

图片
Uniconazole is a triazole plant growth regulator widely used in cotton production. In recent years, it has an obvious effect on controlling the growth of cotton, promoting flowers and peaches, and can also increase the ratio of cotton double bolls. Welcomed by some cotton farmers.  Today, I will introduce to you a new type of plant growth regualtor, which is more effective than Uniconazole. It is better than Uniconazole because it is not prone to premature aging and defertilization of cotton. 1. What is prohexadione calcium Prohexadione calcium is a new type of plant growth regulator developed by Japan Combina Chemical Industry Co., Ltd. It interferes with the synthesis of gibberellic acid in plants, reduces the content of gibberellic acid in plants, controls leggy growth, promotes flowering and fruiting, and increases yield. Make its root system developed, protect cell membrane and organelle membrane, and improve crop resistance ability. So as to inhibit the upper vegetative growth of
