Technical Field
The invention relates to the technical field of plant growth regulation in the planting industry, in particular to a preparation method and a use method of a green crop vigorous growth control product.
Background
Due to the fact that base fertilizers are unscientific in use and the factors such as organic fertilizers rich in quick-acting nitrogen, manure or excessive fertilizers lead to vigorous growth of crops in seedling stage, influence on reproductive growth of crops, delay flowering results, decrease in yield of agricultural products and even reduction in quality.
Vigorous growth is the problem of crop growth obstacle frequently occurring in planting management, and the existing solution is to apply chemical vigorous-control products, such as paclobutrazol, mepiquat chloride, uniconazole, prochloraz, tebuconazole and other plant growth regulators.
Chemical vigorous-control products represented by artificially synthesized plant growth regulators are widely applied in the planting industry practice, and although the problem of vigorous growth of crops is solved to a certain extent, the chemical vigorous-control products also bring many negative problems:
(1) causing phytotoxicity to crops and influencing reproductive growth. Such phytotoxicity is classified into dominant phytotoxicity (e.g., visually inhibiting growth or even death) and recessive phytotoxicity (delayed flowering and fruiting, decreased yield, decreased quality).
(2) There is a residual risk and threatens food safety. The problem of residue and health risks of chemical thriving control agents have received close attention by the public and government.

Drawings
FIG. 1 is a comparison of treated and untreated watermelon seedlings according to the present invention (left is treated watermelon seedling according to the present invention, right is untreated watermelon seedling).
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example 1: the Ascophyllum nodosum extract and the Ruppia maritima extract were mixed in a ratio of 3: 2 in proportion
300 ml of Ascophyllum nodosum extract and 200 ml of Ruppia maritima extract are measured and uniformly mixed to prepare the stable and uniform aqua PJ-A32.
PJ-A32 is used at 2.5 leaf stage of pepper seedling, once in 11 months, 12 months and 1 month in 2020, 3 times for total, the dosage per mu is 100ml, and the solution is diluted to 300 times of dripping roots by adding water.
The contrast agent is 25% propiconazole missible oil which is diluted to 1500 times of leaf spraying, the spraying amount per mu is 30 liters, and the leaf spraying is carried out 15 days before transplanting in 1 month of 2020.
Measuring the height of main stems and the fresh weight of root systems on the same day of transplanting; observing the seedling revival rate 7 days after transplanting; observing the survival rate 30 days after transplanting; record final red pepper yield:
and (3) test treatment: PJ-A32; stem height (cm): 27.8; reduction of stem height (%): 27.4; root weight (g): 5.2; root weight/stem height: 0.19; seedling recovery (%): 83.4; survival rate (%): 99.1; yield per mu (kg): 3108.7, respectively; yield increase (%): 16.3;
and (3) test treatment: 25% propiconazole; stem height (cm): 24.9; reduction of stem height (%): 35.0; root weight (g): 3.9; root weight/stem height: 0.16; seedling recovery (%): 70.6; survival rate (%): 97.6; yield per mu (kg): 2890.4, respectively; yield increase (%): 8.1;
and (3) test treatment: no processing (CK); stem height (cm): 38.3; reduction of stem height (%): - -; root weight (g): 5.5; root weight/stem height: 0.14; seedling recovery (%): 79.7; survival rate (%): 94.0; yield per mu (kg): 2672.7, respectively; yield increase (%): - -;
the test results show that compared with CK, the plant height of the PJ-A32 prepared by the method is effectively controlled, and although the plant height of the 25% propiconazole treatment plant is lower, the PJ-A32 treatment is obviously superior to the 25% propiconazole treatment in root system fresh weight (root weight/stem height), seedling recovery rate and yield increase amplitude.
Example 2: the Ascophyllum nodosum extract and the Potamogeton pecmatous extract were mixed in a ratio of 4: 1 in proportion
Weighing 400 ml of Ascophyllum nodosum extract and 100ml of Potamogeton pecmatous extract, mixing and shaking uniformly to obtain a stable and uniform aqueous solution PJ-B41.
PJ-B41 is used at the 2.5 leaf stage of strawberry seedling, 1 time per month for 4-8 months, 5 times for total, the dosage per mu is 100ml, and diluted with water to 300 times of drenching root.
The contrast agent is 25% prochloraz emulsifiable solution, 600 times of the prochloraz emulsifiable solution is sprayed, the spraying amount per mu is 30 liters, the spraying amount per mu is 5-8 months, and the control agent is continuously used for 7 times.
Measuring the plant height and the fresh weight of root systems on the same day of transplanting; observing the seedling revival rate 10 days after transplanting; observing the survival rate 45 days after transplanting; recording the initial flowering phase:
and (3) test treatment: PJ-B41; plant height (cm): 16.1; plant height reduction (%): 47.7; root weight (g): 7.4 of the total weight of the mixture; root weight/plant height: 0.46 of; seedling recovery (%): 94.3; survival rate (%): 96.7 parts of; beginning of flowering period: 10 months and 21 days;
and (3) test treatment: 25% prochloraz; plant height (cm): 13.7; plant height reduction (%): 55.5; root weight (g): 5.5; root weight/plant height: 0.40; seedling recovery (%): 86.8 of the total weight of the powder; survival rate (%): 91.4; beginning of flowering period: 10 months and 27 days;
and (3) test treatment: no processing (CK); plant height (cm): 30.8 of the total weight of the mixture; plant height reduction (%): - -; root weight (g): 8.4 of the total weight of the mixture; root weight/plant height: 0.27; seedling recovery (%): 88.3; survival rate (%): 89.5; beginning of flowering period: 10 months and 24 days;
from the test results, it can be found that the height of the strain is reduced by 47.7% compared with that of CK strain by the PJ-B41 treatment, and the reduction degree is lower than 25% of prochloraz treatment, but the reduction degree has remarkable advantages in root weight/plant height ratio, seedling revival rate, survival rate and flowering time.
Example 3: the Ascophyllum nodosum extract and the Sargassum thunbergii extract were mixed as follows 5: 2 in proportion
Weighing 500 ml of Ascophyllum nodosum extract and 200 ml of Sargassum thunbergii extract, mixing and shaking uniformly to obtain the stable and uniform water aqua PJ-C52.
PJ-C52 is sprayed with 300 times of liquid leaves when the watermelon seedlings are flat, and is used once in the whole seedbed stage.
The control agent is 15% paclobutrazol, which is sprayed at the same stage with the concentration of 10mg/L on the leaves, and is used once in the whole seedbed stage.
Transplanting in a three-leaf one-heart period, and measuring the plant height and the root length on the same day of transplanting; observing the seedling revival rate 7 days after transplanting; recording the initial flowering phase:
and (3) test treatment: PJ-C52; plant height (cm): 12.9 of the total weight of the mixture; plant height reduction (%): 29.5; root length (cm): 6.5; root-crown ratio: 0.50; seedling recovery (%): 99.0; beginning of flowering period: 6 months and 4 days;
and (3) test treatment: 15% paclobutrazol; plant height (cm): 12.1; plant height reduction (%): 33.9 of the total weight of the alloy; root length (cm): 5.1; root-crown ratio: 0.42; seedling recovery (%): 94.8 of the total weight of the powder; beginning of flowering period: 6 months and 10 days;
and (3) test treatment: no processing (CK); plant height (cm): 18.3; plant height reduction (%): - -; root length (cm): 5.7; root-crown ratio: 0.31; seedling recovery (%): 95.2; beginning of flowering period: 6 months and 7 days;
from the test results, the PJ-C52 treatment is close to paclobutrazol in plant height reduction, the difference is not obvious, but the root-crown ratio is obviously superior to that of the control and paclobutrazol, the seedling recovery is fast after transplanting, and the flowering time is 6 days earlier than that of the paclobutrazol treatment.
