Embodiment 1

[0023] 1. Granule production method (please refer to figure 1 )

[0024] (1) Get 65 parts of zinc sulfate monohydrate as trace element fertilizer, 15% paclobutrazol wettable powder (it is processed by 95% paclobutrazol former medicine and suitable auxiliary agent and filler. National standard stipulates that in 15% paclobutrazol wettable powder Pure paclobutrazol mass percentage is 15%) 25 parts, according to above-mentioned weight ratio batching, mix, pass ≥ 70 mesh sieves, the powder after mixing sieving is sent to granulator, and described granulator can be spherical body granulation machine.

[0025] (2) Use a high-pressure pump to send water to the atomizing head of the granulator, and start the granulator at the same time for granulation.

[0026] (3) The shaped particles are sent to drying equipment for drying, and the drying equipment can be a hot air blower, a drying bed, etc.

[0027] (4) Sieve the dried granular product and pack it into bags. The spherical produc...

Embodiment 2

[0039] Take 75 parts of trace element fertilizer zinc sulfate monohydrate and 15 parts of 15% paclobutrazol wettable powder respectively by weight, and set aside.

[0040] Its preparation method is the same as that of Example 1 and will not be repeated here.

[0041] In 2011, a comparative test was carried out between the application of Example 2 and no application (control) on the middle rice "Liangyoupeijiu", and the results are as follows:

[0042]

[0043] As can be seen from the above table, after using the granule preparation of Example 2, compared with no application, the effective panicle is increased by 10.4%, the yield is increased by 10.1%, and the plant height is reduced by 7.2 centimeters.

Embodiment 3

[0045] Take 70 parts of trace element fertilizer zinc sulfate monohydrate and 21 parts of 15% paclobutrazol wettable powder respectively by weight, and set aside.

[0046] Its preparation method is the same as that of Example 1 and will not be repeated here.

[0047] In 2011, the application of Example 3 and no application (control) on the middle rice "Yangliangyou No. 6" was used as a comparative test, and the results were as follows:

[0048]

[0049] As can be seen from the above table, after using the granule preparation of Example 3, compared with no application, the effective panicle is increased by 14.2%, the yield is increased by 14.0%, and the plant height is reduced by 9.6 cm.

Abstract

The invention discloses a granular preparation for promoting rice tillering. The granular preparation is prepared from the following raw materials in parts by weight: 65-75 parts of monohydrate zinc sulfate and 15-25 parts of a 15 percent paclobutrazol wettable powder. The granular preparation contains a plant growth retardant, i.e., the 15 percent paclobutrazol wettable powder, so that the granular preparation is particularly suitable to be applied after transplanting and root survival of rice, rice roots can be developed, white roots are increased, tillering and low-position tillering are put forward, absolute plants and yield are increased by over 10 percent, leaves are green, stalks are strong, internode elongation is controlled, the plant height is reduced by 7-11 centimeters, lodging is prevented to the maximum extent, the effect of increasing both production and income is achieved, and the problem of reduction in production caused by small tillering and easiness in lodging of rice is well solved; due to the adoption of monohydrate zinc sulfate, the occurrence of stifling, runt seedling and 'dwarf disease' of rice can be prevented effectively, growth and tillering are promoted, the drought resistance and low temperature resistance of rice is enhanced, and a good yield increasing effect is achieved; and the granular preparation is of a size which is consistent with those of urea particles, is convenient to apply together with other preparations, and has a better effect.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizer production, in particular to a granular preparation for promoting rice tillering. Background technique [0002] Rice has tillering properties. The tillering of rice is carried out according to the rule of simultaneous extension of leaves and tillers. Rice tillers mostly occur at the very short tiller nodes at the basal internodes. The lower the tiller position, the earlier the tiller occurs, the more leaves on the tiller, and the greater the possibility of forming an ear. This kind of tiller is called an effective tiller. Most of the high-tiller position tillers born late cannot form ears, which are called invalid tillers. The number of tillers sooner or later is closely related to the depth of transplanting, temperature, light, water, and nutrient supply. Therefore, effective measures should be taken in production to strive for early tillering, multiple tillering and low tille...
