#Agricultural Technology Science Competition #Brassicalin and Gibberellin are two high-quality plant production regulators in agricultural production, and farmers use them a lot in the specific production process in rural areas. Their good and high-volume effects are really liked by everyone and loved by farmers.
Brassinolide is an excellent crop growth regulator, a very high biological activity in steroidal compounds, and is widely present in crops. Low concentration of brassinolide can promote growth on crops, increase nutrient harvest, improve fruit set rate, promote fruit hypertrophy, increase 1,000 grain weight, improve crop hardiness, have cold resistance, reduce fertilizer damage, and increase disease resistance. Brassinolide has the effect of enhancing plant vegetative growth, promoting cell division and growth.
Gibberellin is a kind of kayperene compound, is a broad-spectrum plant growth regulator, plant body commonly exists natural endogenous gibberellin, is one of the important hormones to promote plant growth and development. It is synthesized in plants, in germinating seeds, young shoots, growing leaves, blooming flowers, stamens, pollen grains, fruits, and roots.
The root synthesis of gibberellin in the crop moves upwards, while the synthetic gibberellin at the top moves downwards, and the transport site is in the phloem cortex, and the speed of transport is comparable to the speed of movement of photosynthetic products.
Artificial production of synthetic gibberellin, mainly through the leaves, young branches, flowers, seeds, fruits absorption and utilization, moved to the part of action, has a variety of physiological effects, has changed the proportion of certain crops, male flowers, induce unisexual fruiting, accelerate the growth of certain crops, promote fruit set, break the dormancy of seeds, early seed germination, accelerate the growth of stems, and the extraction of certain crops.
There is enlargement of leaf area, accelerating the growth of young branches, which is conducive to the accumulation of the inner surface of the soft skin of metabolites, activating the formation layer, inhibiting maturity, senescence, lateral bud dormancy, and the formation of tubers.
In rural areas, farmers can be gibberellin and brassinoin compound, there are many effects, the following brief introduction, several important common effects, to help farmers solve these problems.
(1) Break the dormancy period. If potatoes, ginger, sweet potatoes, taro, sugarcane and other crop seeds are not germinated when sown, they can use brassinolide and gibberellin compound solution spray or low concentration soaking, which will break the dormancy period and germinate within a few days, which can improve the germination rate of seeds. Other crop seeds can also be treated with this solution, which will speed up seed germination and reduce the degree of bad seed.
(2), prevention and control of fertilizer damage. When farmers fertilize crops and spray pesticides, they are very prone to fertilizer and drug damage. When farmers fertilize and spray pesticides on crops, when they find that there is fertilizer damage, the use of this compound solution immediately can well alleviate the damage caused by the crop and turn the crisis into safety.
(3) Improve drought resistance. Both brassinolide and gibberellin have the effect of promoting root growth in crops. When crops encounter drought, the roots are deep into the soil, and the deeper the roots are rooted, the more water can be absorbed to alleviate the drought state of the crop. Therefore, it is possible to make crops achieve drought resistance.
(4) Improve cold resistance. Both agents have two different growth effects, cultivating robust young fruits of crops. When the temperature is low, the crop body stimulates the crop cells to produce enough energy to increase the physiological temperature of the plant, achieve the effect of cold protection and warmth, and do not cause the crop to be affected by cold freezing.
(5), promote growth. This compound agent has promoted the rapid growth of crops. When crops encounter cold, drought, drug damage, fertilizer damage, lack of nutrients, etc., it can quickly promote the growth and development of crops.
(6), keep flowers and fruits. When crops are flowering and bearing fruit, due to the lack of nutrients in crops, it is easy to cause flowers and fruits to fall. By using the compound solution foliar spray, it can regulate the physiological functions in the crop body, promote the rapid absorption of nutrients by the roots, accelerate the transmission of nutrients in the body, and promote the effect of flower preservation and fruit preservation.
All in all, when using these two plant growth regulators, the gibberellin concentration is 15 to 20 mg / l, and brassinolide is usually 0.02 ~ 0.04 mg / l, for compounding, even spray or soaking.
