Taboos for fertilization of honeysuckle
As a traditional plant with the same origin as medicine and food, scientific fertilization directly affects the flowering quality and medicinal value. Many growers cause their plants to wither due to improper fertilization. This article systematically analyzes the four major fertilization misunderstandings that must be avoided during honeysuckle cultivation to help you cultivate healthy and lush honeysuckle plants. In-depth analysis of fertilization taboos for new plants during rootless period, fertilization taboos for cuttage propagation of honeysuckle needs to go through a rooting period of 2-3 weeks, when the root system does not form an absorption network. Experimental data show that premature fertilization will increase the EC value of the substrate to more than 1.5mS/cm, directly damaging the new root primaries. It is recommended to apply a water-soluble fertilizer containing humic acid diluted 2000 times to promote roots after the new buds have unfolded 3-4 pairs of true leaves. Fertilization taboo in high temperature seasons When the temperature continues to be higher than 35℃, honeysuckle will activate its self-protection mechanism, the stomatal closure rate will increase by 68%, and the nutrient absorption efficiency will drop to 40% of the normal level. Fertilization at this stage can easily cause salt accumulation. Typical cases show that wrong fertilization can increase soil hardening by 30%. It is recommended to use foliar spraying 0.1% potassium dihydrogen phosphate solution to cooperate with sunshade nets. The roots of honeysuckle are extremely sensitive to salt concentration when the fertilizer concentration exceeds 0.3%. Studies have confirmed that when the fertilizer concentration exceeds 0.3%, the root hair cells will have plasmatic wall separation. It is recommended to use the "secondary dilution method": first prepare the fertilizer into mother liquor, and then add water to apply it at a ratio of 1:50. Organic fertilizers must be decomposed for more than 3 months to avoid the production of harmful gases such as hydrogen sulfide. Water shortage after fertilization is prohibited. Irrigation with "fixed root water" must be carried out within 24 hours after fertilization. The optimal watering amount is 5L/m². Water dilutes fertilizer concentrations to safe ranges and promotes nutrient migration to the rhizosphere. Comparative tests showed that the fertilizer utilization rate of plants watered in time increased by 42%, and the chlorophyll content of leaves increased by 25%.
Master the "three-season fertilization method" of honeysuckle: apply nitrogen, phosphorus and potassium balanced fertilizers during spring germination period, add boron and zinc trace fertilizers during flower bud period, and supplement organic fertilizers before overwintering. Combined with the fertilization taboos avoidance measures described in this article, the yield of honeysuckle can be increased by more than 30%, and the content of chlorogenic acid, the active ingredient, can be stabilized in the high-quality range of 5.2%-6.8%.
