The present invention utilizes the withered powder of tea and the above-mentioned characteristic of nereistoxin insecticide, and both have the diverse mechanism of action, carries out soil treatment by after both are composite, can significantly reduce worm source, field radix, greatly reduces the usage amount of chemical agent.
Embodiment
The small plot experiment case:
1, reagent agent:
(1) the withered powder of tea, the contrast medicament provides test specimen by manufacturer.
(2) compounding powder agent, take the withered powder of tea as carrier, need (seeing that specifically 2 is described) to add the withered powder of tea the desinsection individual palpation after, fully grind and stir, namely make compounding powder agent.
2, test method:
About 0.02 mu of small plot experiment area, test site are Milky Way Da Feng proving ground, Guangzhou.Each medicament arranges 3 processing, and wherein the withered powder single dose of tea is processed by 60,30 and 10 kg/acres consumption respectively; Compounding powder agent is pressed the consumption of 10 kg/acres in the withered powder of tea, add respectively 500,200 and 100g desinsection list process.Selecting the brassicaceous vegetable kind is 50d cabbage heart (Brassica campestris L.), and seeding quantity is by 1 kg/acre.
Each treatment agent and cabbage heart mixing are also arranged district by district sowing by processing.Gauze on the trickle bonnet.Any processing is not carried out in contrast, and other management are with conventional.Each is processed and repeats randomized arrangement 3 times.
Solarium's small plot experiment is investigated weekly seedling number, is taken food hole count, takes off net and investigation seedling number the 4th week, takes food hole count, lays particular stress on the investigation medicament to the impact of colza emergence rate and the rate of growth of keeping a full stand of seedings.
3, result and analysis
Small plot experiment result shows, increase with consumption improves the withered powder single dose of tea to the deterrent effect of phyllotreta striolata adult, shows to take food the corresponding minimizing of hole count, but finds simultaneously when the withered powder consumption increasing of tea, can to a certain degree affect the seed sprouting number, cause production declining.Compare with single dose, during with the withered powder of tea and the composite use of desinsection list phyllotreta striolata is shown preferably control efficiency, but control efficiency does not become positive correlation with desinsection list addition.And find the fertilizer efficiency that this compounding powder agent is certain, be embodied in emerge several more, take food that the hole is less, the dish output increased, specifically see Table 1.
