Background technology
The inventor is that CN1062416C, denomination of invention are in the patent documentation of " a kind of agricultural chemicals " at notification number, disclose a kind of by bactericide pcnb and copper sulphate, auximone 920, the agricultural chemicals that trace element fertilizer potassium sulphate, zinc sulphate, boric acid and filler mixed preparing form.Though this agricultural chemicals can be used for the roots of various vegetables, economy and cereal crops and soil sterilization, sterilization, can also strengthen the ability of the disease resistance of crop simultaneously, promote advantages such as diseased plant rehabilitation.But since in the pcnb chloride essence and in soil residual life long, and Capsicum is avoided the chlorine plant, residual chlorine is big to the harmfulness of capsicum in chlorine in the bactericide (agricultural chemicals) or the soil.Thereby the above-mentioned agricultural chemicals that contains pcnb can not be used for the disease control of capsicum and plan be planted the sterilization of capsicum soil; In addition, agricultural chemicals also has certain side effect to plant when preventing and treating disease, though added multiple little fertilizer in the above-mentioned prescription, its effect is more slow relatively.Thereby background technology exists because of big to the harmfulness of avoiding chlorine plant capsicum, thereby can not be used for diseases prevention and the somatotrophic preparation of chili growth phase, particularly growth of seedling phase as agricultural chemicals etc. and use.
Summary of the invention
The objective of the invention is research, a kind of seedling stage of red pepper seedling stage of preparation with diseases prevention and growth promotion double-efficacy composite preparation, when effectively preventing pepper seedling disease in vegetative period, promote growth, the growth of (stimulation) root system and plant, improve the immunity of plant and the ability of disease resistance, it is numerous, full of leaves to reach root, purpose such as finally increases production, increase income.
Solution of the present invention is on basis of background technology, cancel the bactericide pcnb and the copper sulphate of chloride element, change into having more broad spectrum activity and combining the systemic fungicide that further suppresses the germ sprouting and dislike mould spirit with iron, the aluminium ion in the soil, increase the quick-acting nitrogenous fertilizer urea of chloride element not simultaneously and adjust the ratio of each component, thereby realize its goal of the invention.Therefore, compound formulation of the present invention comprises bactericide, auximone 920 and trace element fertilizer potassium sulphate, zinc sulphate, boric acid, and key is also to comprise in its component nitrogenous fertilizer urea, bactericide is then for disliking mould spirit; Each composition with dislike mould spirit be benchmark by weight, be respectively: dislike mould clever 1 part, 2~3 parts in urea, 1.2~2 parts of potassium sulphates, each 0.8~1.2 part in zinc sulphate, boric acid, growth hormone 920 is 0.004~0.005 part, mixed preparing forms.In described each composition: disliking mould clever purity is 95%, total nitrogen in the urea (N) content 46%, and all the other each composition purity are all by 98%.
Above-mentioned nitrogenous fertilizer urea can adopt the suitable ammonium carbonate of total nitrogen (N) content to replace.And described growth hormone 920 is water solube powder.
The present invention is owing to adopt the mould spirit of evil to replace bactericide pcnb and copper sulphate, thereby both avoided in the bactericide chlorine element to the harm of pepper seedling, utilize the mould spirit of evil to produce glucosides again at the pepper seedling internal metabolism, activate the growth mechanism of root, promote root growth, can in body, cut off the biological chain that pathogen depends on for existence rapidly, the directly two-way function of killing pathogenic bacteria simultaneously, in prescription, increase instant nitrogenousfertilizer urea etc. in addition, replenished nutriment rapidly; Thereby have when effectively preventing the pepper seedling disease, promote the plant root growth, grow, further improve the ability of its immunity and disease resistance, thereby make the plant root numerous, full of leaves, characteristics such as final realization volume increase.
Embodiment
The present embodiment prescription is: purity is 95% the mould clever 1.2kg of evil, total nitrogen (N) content is 46% urea 3.0kg, the potassium sulphate 2.0kg of purity 98%, purity is zinc sulphate and each 1.0kg of boric acid of 98%, purity is 98% auximone 920 water soluble powder 5g; After fully mixing, vacuum-packed.
The compound formulation of present embodiment preparation can be used for 7~12 days seedling of one mu of field planting.Can be at first before using be made into stoste (dope), again the clear water total amount be added to about 1000kg the root filling of dilution back when using and use with the clear water of 1~2 times of weight of formulation.
