Problems solved by technology

The harm of flying catkins is mainly manifested in three aspects: the first is that flying catkins are easy to carry pollutant particles, heavy metals and other harmful substances. Inhalation into the nostrils can aggravate respiratory diseases such as asthma and chronic bronchitis, and cause harm to ...

preparation example 1

[0064] After dissolving 350g of the original drug 2,4-dinitro-N3,N3-dipropyl-6-trifluorotoluene-1,3-diamine in 500g of xylene solvent and fully dissolving, add 30 grams of NP-10 and 30 grams of Span-80 two emulsifiers, fully stirred, made into emulsifiable concentrate, then added 40g glycerol as antifreeze, 2g polydimethylsiloxane as defoamer, 25g naphthalenesulfonate formaldehyde condensate as Dispersant, 1g of ethyl p-hydroxybenzoate sodium salt as a stabilizer, if less than 1000g, use xylene as a solvent to make up, and finally fully stirred, and made into emulsifiable concentrate to obtain the target drug - self-made flower bud differentiation inhibitor.

[0065] The self-made flower bud differentiation inhibitors in Preparation Examples 2-5 were carried out according to the method in Preparation Example 1, the difference being that each preparation example was configured according to the amount of each raw material in Table 1 to obtain the self-made flower bud differentiat...

preparation example 6

[0069] The self-made flower bud differentiation inhibitor is carried out according to the method of Preparation Example 1, the difference is that the original drug is selected from 2,4-dinitro-N3,N3-dipropyl-6-trifluorotoluene-1,3-diamine and N-(cyclopropylmethyl)-2,6-dinitro-N-propyl-4-(trifluoromethyl)-aniline was mixed in a 1:1 ratio.

preparation example 7

[0071] The self-made flower bud differentiation inhibitor is carried out according to the method of Preparation Example 1, the difference is that the original drug is selected from 1,2-dihydro-3,6-pyridazinedione and N-(cyclopropylmethyl)-2, 6-Dinitro-N-propyl-4-(trifluoromethyl)-aniline was mixed in a ratio of 4:5.

Abstract

The invention discloses a method for inhibiting tree seeds from producing flying catkins or flying fluffs. The method comprises the following step of spraying a self-prepared bud differentiation inhibiting agent to leaves of the tree seeds according to the crude drug concentration of 1.6 g/L to 51.2 g/L one to fifty days before the bud physiological differentiation stage of the tree seeds, or injecting the self-prepared bud differentiation inhibiting agent into a tree seed trunk according to the crude drug dosage of 3.2 g/dm to 51.2 g/dm, wherein the self-prepared bud differentiation inhibiting agent is prepared from the following raw materials in 1,000 parts by weight: 5 to 660 parts of crude drug and the balance of additive; the crude drug is compounded by any one or two of 1,2-dihydro-3,6-pyridazine diketone and dinitrobenzene amine weeding agents according to any ratio. The method has the advantage that the method can be used for inhibiting the tree seeds from producing the flyingcatkins or flying fluffs.

Description

technical field [0001] The invention relates to the field of landscaping, more specifically, it relates to a method for inhibiting tree species from producing flying catkins or flying hairs. Background technique [0002] The leaves of willow and sycamore are dense and have strong shading ability. They can not only provide good shade and lower the temperature in hot summer, but also shed leaves in cold winter without blocking the sun. Therefore, willow is very popular in cities in northern China. Widely planted, Platanus is widely planted in cities along the Yangtze River to the Yellow River valley in China. What follows is that urban residents often suffer from flying catkins produced by willows and sycamores in spring (Tang Xiaolan et al. 2014. Allergies of two common street trees in Nanjing and their control measures. Journal of Jishou University ( Natural Science Edition), 35(3):69-73,92). [0003] Willow catkins are appendages of the seeds of poplar and willow plants, ...
