April 12 observed: use the capsicum of 25% first piperazine aqua compared with the control, Dwarf Effect on Dwarf is better; Capsicum and the contrast ratio of using 0.1% triacontanol microemulsion, flower and fruit protecting effect is better; Use capsicum and the contrast ratio of first piperazine proportioning microemulsions different from triacontanol, Dwarf Effect on Dwarf and flower and fruit protecting effect are all better.
April 29 observed: use the capsicum of 25% first piperazine aqua compared with the control, Dwarf Effect on Dwarf and the effect of expanding are better; Capsicum and the contrast ratio of using 0.1% triacontanol microemulsion, flower and fruit protecting effect is better; Use capsicum and the contrast ratio of first piperazine proportioning microemulsions different from triacontanol, Dwarf Effect on Dwarf and flower and fruit protecting effect, the effect of expanding are all better.
Statistics capsicum plant height, hectare output, dwarfing rate, rate of growth, the results are shown in Table 2.
Table 2 test determination data:
Effect is evaluated:
25% first piperazine aqua, 0.1% triacontanol microemulsion are within the scope of application concentration, to capsicum safety, without any poisoning.
25% first piperazine aqua can effectively be controlled pepper plant height after using, and the capsicum plant height after processing is all lower than blank, and application concentration is larger, and dwarfing effect is more obvious, but working concentration is not directly proportional to rate of growth; 0.1% triacontanol microemulsion is used and can not be suppressed pepper plant height, because it has the characteristic that promotes cauline leaf growth, can not control plant and grow in length and breadth, and plant height increases on the contrary to some extent; The composite microemulsion of first piperazine and triacontanol utilizes first piperazine can effectively control pepper plant plant height, the characteristic that delays to nourish and grow, in conjunction with triacontanol, improve the effect of ripening rate and increase dry-matter accumulation, not only plant height is lower than blank, and rate of growth is than blank and use separately first piperazine, triacontanol to increase substantially.Wherein first piperazine and triacontanol are according to the composite microemulsion of the weight ratio of 600:1 (30mg/kg first piperazine+0.05mg/kg triacontanol), and rate of growth can reach 26.50%, and difference is extremely remarkable.
The capsicum that 25% first piperazine aqua and 0.1% triacontanol microemulsion are used respectively has volume increase in various degree than blank, rate of growth is between 1.29%-14.83%, and the capsicum that the first piperazine microemulsion composite with triacontanol used has been compared obvious volume increase with blank, rate of growth is at 9.55%-26.50%, and difference is extremely remarkable.
The above results shows, first piperazine and triacontanol composite use are by a certain percentage had to flower and fruit protecting, improve output, improve quality, increase the effect of resistance.
The explanation of above embodiment is just for helping to understand method of the present invention and core concept thereof.It should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention, can also carry out some improvement and modification to the present invention, these improvement and modification also fall in the protection domain of the claims in the present invention.
