Description
Technical Field
The invention relates to the field of agricultural crop growth control, in particular to a plant growth regulator composition containing prohexadione calcium and triacontanol and application thereof, and in particular relates to application to peanut growth regulation to realize peanut yield improvement.
Background
Peanut is an important oil crop in China and is an important edible oil source. The peanut production plays an important role in improving the income of farmers, enhancing the national oil safety and adjusting the rural industrial structure. At present, plant growth regulators are generally sprayed at the middle and later stages of peanut growth to control or promote the growth, and the growth of the peanuts is controlled through coordination of the control of the growth and the promotion of the growth, so that the plants of the peanuts are strong, nutrition growth and reproductive growth reach balance, and the effects of stress resistance and the like are realized, but the value of the peanut is finally reflected in the improvement of the peanut yield.
The spraying of triacontanol on peanuts has the effect of promoting the criminal investigation on the nutrition growth. The spraying effect is obvious in seedling stage and flowering stage, the branch number, the leaf number and the leaf area of a single plant are all increased, and the accumulation of dry matters on the ground and underground parts is promoted. But the spraying concentration is too low to achieve the effect. The pod stage spraying increases ineffective flowers and fruit needles in the later stage instead, and gradually increases with the increase of the concentration. The spraying energy in seedling stage and flowering stage can increase the amount of flowers, the flowering stage is shortened, the flowering peak is advanced, the flowering stage is relatively concentrated, the number of single plant fruits, the number of full fruits, the weight of double kernel fruits and hundred fruits are increased, the kernel yield is increased, and the number of blighted fruits and young fruits is relatively reduced. The pod-stage spraying has opposite effects, which can reduce peanut yield.
The prohexadione calcium is mainly applied to crops such as rice, peanut, wheat and the like at present, and the foliar spray of the prohexadione calcium at the end stage of peanut blossom is effective in controlling the vegetative growth of the overground parts of the peanut, improving the number of kernels, the quality of hundred fruits and the pod yield, and the prohexadione calcium starts to have the flourishing control effect within 7 days after the application of the pesticide, and is reduced from 14 days after the application of the pesticide to the day of harvest. The foliar spray is carried out from the end stage of peanut blossom to the pod bearing stage, so that the yield increase effect is achieved on the peanuts.
Because the action directions of the triacontanol and the prohexadione calcium are different and even the opposite action is performed, no report of balancing and regulating peanut growth by compounding the triacontanol and the prohexadione calcium is explored in peanut production practice. In order to solve the problem of growth regulation of peanuts, realize the regulation of nutrient growth and reproductive growth of the peanuts so as to greatly improve the yield of the peanuts, the selection of the variety of the medicament for regulating and controlling the growth of the peanuts is needed, including development and market application of the compound medicament.

Specifically, the invention provides a peanut growth regulator composition containing triacontanol and prohexadione calcium, which is characterized by comprising triacontanol and prohexadione calcium in a mass ratio of 1-3:98.
Preferably, in the plant growth regulator composition, the mass ratio of triacontanol to prohexadione calcium is 2:98 (simplified structure is 1:49).
Preferably, the formulation of the composition is not limited to wettable powder, soluble powder, water dispersible granule, suspending agent, emulsifiable concentrate, aqueous emulsion, microemulsion, powder, granule, effervescent tablet, dispersible tablet or microcapsule, and preferably, the formulation of the composition is suspending agent.

The beneficial effects of the invention are that
After the invention is applied to peanuts through the compound of triacontanol and the calcium propiolate, the peanut yield is obviously improved, and the triacontanol and the calcium propiolate have obvious synergistic effect under the condition of the mass ratio of 1:49 on the index of improving the peanut yield. Although the use of triacontanol and prohexadione calcium alone can also increase peanut yield, there are significant limitations in yield increase and dosing control is critical. When triacontanol is used for promoting growth, excessive application of the pesticide can cause overgrowth of nutrition, nutrition supply for reproductive growth is reduced, and yield is reduced; similarly, excessive dosage of calcium propiolate alone can cause excessive inhibition of peanut nutrition growth, the nutrition growth supplied to reproductive growth becomes a short plate, nutrition required by reproductive growth is not enough to be drawn from the nutrition growth, and the peanut yield is reduced.
Experiments of the invention show that the selection of the proportion of the triacontanol and the prohexadione calcium is very critical, the yield increase amplitude which can be realized by the two compounds and applied to peanuts is also very large under the condition that the mass ratio is 1:98 and 3:98, the yield is respectively improved by 14% and more than 20%, but the synergistic effect of the triacontanol and the prohexadione calcium is only an addition effect, the synergistic effect is not realized, and under the condition that the mass ratio is 1:49, the triacontanol and the prohexadione calcium realize remarkable synergistic effect, and the actual yield is 13.40% higher than the theoretical yield. Therefore, the invention compounds triacontanol and the prohexadione calcium with the mass ratio of 1:49 for regulating the growth of the peanuts, solves the problems of regulating and controlling the nutrition growth and balanced reproductive growth of the peanuts, realizes the reduction and synergy of pesticide use, and provides a new choice for the realization of the yield increase of the peanuts and the reduction and synergy of the pesticide.
Detailed Description
The following examples were prepared from 0.1%, 0.2%, 0.3% triacontanol microemulsion, 9.8% prohexadione calcium suspension, and 0.1% 9.8%, 0.2% 9.8%, 0.3% 9.8% triacontanol calcium suspension.
The yield increase in the following examples was calculated according to the following formula.
Actual yield increase E (%) = [ (agent treated yield-blank yield)/blank yield ] ×100
The theoretical yield of the two agents for compounding application is calculated according to the following formula, and the unit is percentage (%).
E0＝X+Y-XY/100
Wherein:
e0 is theoretical yield increase after the compound application of the triacontanol with the dosage of P and the dosage of the prohexadione calcium with the dosage of Q;
x is the yield increase rate when the triacontanol dosage is P;
y is the yield increase rate when the dosage of the prohexadione calcium is Q; .
E is the actual yield increase rate of the triacontanol and the prohexadione calcium compound application, and the rationality of the combined action type and the proportion of the mixture is evaluated according to the Gowing method recommended by NY/T2061.5-2016. Namely: E-E0 > 10% is synergistic; less than-10% of E-E0 is antagonism; E-E0 values between-10% and 10% are additive.
Examples
The test land is arranged in Taian city of Shandong province, the test crop is peanut, the variety is "flower cultivation No. 20", the variety is common small nut peanut variety, the peanut is planted in a large-ridge double-row mode, the ridge distance is 75cm, the row distance is 25cm, the hole distance is 20cm, and 2 plants are planted in each hole. The crops planted in the previous year of the test land are also peanuts, so the peanuts planted in the test are planted in continuous cropping. The sowing time is 2021, 4 months and 19 days, and the growth condition is good. Other plant growth regulators are not used in the test period, the field fertilizer and water and plant diseases and insect pests are strictly managed according to the peanut planting management requirements, and the cultivation management conditions of the test area are uniform and consistent and accord with the local scientific agricultural cultivation measures.
The back carried electric sprayer is used for spraying the liquid medicine on the leaves of the peanut in the flowering period, each treatment is repeated for 4 times, each treatment is repeated for 20 square meters, each treatment is added up to 80 square meters, each repeated medicine use is 1 liter, and the liquid medicine spraying amount per hectare is 500L. Wherein the blank control is 0.1% Tween aqueous solution, and the amount of the control spraying liquid is the same as that of the liquid medicine sprayed by other medicament treatments. The treatment number, formulation specifications, formulation usage and the amount of active ingredient per hectare for each treatment are shown in Table 1 below.
TABLE 1 treatment settings of triacontanol and prohexadione calcium on peanuts
In table 1 above, the dosage of each formulation treated was 80 square meters, diluted to 4L and sprayed 1L each time.
During the mature peanut harvesting period, each repetition of each treatment is randomly divided into two small blocks with equal areas, one of the small blocks, namely 10 square meters of peanuts, is selected for measuring the yield, 4 small blocks are measured for 4 repetitions, the total of 40 square meters of peanuts are taken as a total sample of yield measurement of each treatment, the peanut yield of each small block of each repetition is counted respectively, and then the average yield of each small block of each treatment is calculated. Specifically, the peanut yield, average yield of small blocks, and yield per hectare converted for each repeated small block are shown in table 2 below.
TABLE 2 measurement of yield of triacontanol and prohexadione calcium treated peanuts
As can be seen from Table 2, the yield of triacontanol increased by 85 kg to 310 kg at an amount of 0.3 to 0.9 g/hectare, and the yield increased by about 370 kg at an amount of 29.4g of the active ingredient for prohexadione calcium hectare. According to the comparison and accounting of the medicament cost of triacontanol and prohexadione calcium and the yield increase gain of peanuts, the spraying of triacontanol and prohexadione calcium is beneficial, but after accounting of the labor cost of single administration, the possible result is that the yield increase is not increased. Therefore, the amount of yield increase is ensured after one administration to offset the administration cost and the investment of the medicament cost, which highlights the important value of single administration of the compound medicament and realizing the synergy.
The synergistic effect of triacontanol and calcium propiolate was calculated from the results of table 2, see table 3 below.
TABLE 3 calculation of synergistic Effect of triacontanol and prohexadione calcium
From the calculation results in table 3, it can be seen that the yield increase of peanuts in 0.1% triacontanol and 9.8% prohexadione calcium compound treatment number 5 reaches more than 14%, and is 3.46% higher than the theoretical yield increase, and the synergistic addition effect is achieved. The yield of peanuts compounded by 0.3% triacontanol and 9.8% prohexadione calcium of treatment number 7 is over 20%, which is 5.18% higher than the theoretical yield, and the synergistic addition effect is realized.
The 0.2% triacontanol and 9.8% prohexadione calcium compound of treatment number 6 realizes that the peanut yield increase is 25.31%, 13.40% higher than the theoretical yield increase, indicating that the triacontanol and the prohexadione calcium have a synergistic effect under the condition of a mass ratio of 1:49.
