Description
Technical Field
The invention belongs to the technical field of mango disaster-resistant weather resistance, and particularly relates to a preparation for realizing yield preservation and avoiding outcrop after mango disaster-resistant weather and a using method thereof.
Background
Mango is a typical tropical fruit. The flowering period of mango planted in China is mostly concentrated in 2-4 months, and the suitable temperature for flowering and fruit setting is 20-30 ℃. However, in many mango planting areas in China, the mango planting area is extremely easy to suffer from low-temperature cold damage (less than or equal to 15 ℃) caused by late spring coldness and continuous overcast and rainy weather or the damage of rapid temperature change caused by low-temperature/high-temperature (30-37 ℃ or even higher) roller coasters, so that the mango is most tender and open, and flowers which are almost not protected easily fall off or mildew and rot and cluster on flower branches, and are difficult to bear fruits; moreover, the attack of ladle splash and heavy wind and hail caused by strong convection weather can destroy the remains, so that the fruit branches just full of young fruits can be changed into batons instantly. Especially when these several kinds of disastrous weather happen successively, it is difficult to escape collecting and transporting dangerously. The severe disaster occurs in Guangxi and Yunnan mango planting areas from 3 to 4 months in 2019, fruit growers want to cry and lacy, and tie up is unfair. However, according to the current technical reports, except for the technical reports of treating tree body wounds and preventing disease and insect spreading after the occurrence of the disaster weather, no technical report of realizing yield preservation and avoiding failure to harvest after the occurrence of the disaster weather exists. In the face of the reality of serious yield reduction and even abstinence, the only method is to promote the plant to re-blossom flowering branches as soon as possible and form the yield again. However, the conventional flower control technology of mangoes adopts plant growth regulators such as paclobutrazol, potassium nitrate and ethephon, or girdling and root cutting of branches and trunks, and the early and late flowering period of the annual first flowering period or sex ratio can only be properly adjusted under normal climatic conditions, so that the technology is not an emergency disaster relief and production protection technology.
Disclosure of Invention
Aiming at the technical problems, the invention aims to provide a preparation for realizing yield preservation and avoiding absolute harvest after mango disastrous weather, and by adopting the preparation to spray mango leaf surfaces, mango can be promoted to rapidly and repeatedly extract new flowering branches to bloom again and form yield again after the mango disastrous weather, so that the yield preservation is realized, and the absolute harvest is avoided.
The invention adopts the following technical scheme to solve the technical problems:
a preparation for realizing yield preservation and avoiding outcrop after mango disaster weather comprises a solution A, a solution B and other plant growth regulators; the solution A is an aqueous solution of compound potassium nitrophenolate or an aqueous solution of compound sodium nitrophenolate; the solution B is a water solution of crystalline potassium fulvate.
The preparation for realizing the purpose of ensuring the production and avoiding the outcrop after the mango disastrous weather is prepared by mixing the solution A and the solution B and then adding the other plant growth regulators.
Further, the volume ratio of the liquid A to the liquid B is 0.5-1.5: 1.
Further, the other plant growth regulators are brassinolide, Lingfasu and spermine.
Furthermore, the brassinolide is added at the concentration of 550-650ppm, the prodigiosin is added at the concentration of 80-120ppm, and the spermine is added at the concentration of 1500-2500 ppm.
Further, the mass concentration of the compound potassium nitrophenolate aqueous solution or the compound sodium nitrophenolate aqueous solution is 4-6%.
Further, the mass concentration of the crystalline potassium fulvate aqueous solution is 8-12%.
The application method of the preparation for realizing production preservation and avoiding extinction after mango disastrous weather comprises the following steps: diluting the preparation for realizing the yield preservation and avoiding the outmost harvest 1000-fold and 5000-fold after the mango disaster weather by using drinking water, spraying the mango leaf surfaces for the first time, and spraying the mango leaf surfaces for the second time after 8-12 days.
The invention has the beneficial effects that: the invention utilizes compound nitrophenol-K/NaAnd physiologically active substances such as brassinolide, Lingfasu, spermine and the like which influence the reproductive growth of plants are prepared into a preparation, and the preparation is sprayed on the leaf surfaces of the mangoes, so that the mangoes can be promoted to be rapidly and repeatedly pumped to blossom new flowering branches again to form the yield again after severe disastrous weather, the yield is preserved, and the outmost harvest is avoided.
Detailed Description
The present invention is further described with reference to specific examples for practicing those skilled in the art in view of the description.
It should be noted that the technical methods described in the following embodiments are all conventional methods unless otherwise specified, and the raw materials and materials are commercially available.
Example 1: the preparation of the preparation for realizing the production preservation and avoiding the outcrop after the mango disaster weather is prepared as follows:
step one, preparing a compound potassium nitrophenolate aqueous solution A with the mass concentration of 5%.
And step two, preparing a crystal type potassium fulvate water solution B with the mass concentration of 10%.
Step three, mixing the A, B aqueous solutions according to the volume ratio of 1:1, and then adding 600ppm brassinolide, 100ppm prodigiosin and 2000ppm spermine according to the concentration to prepare the preparation of the invention.
Example 2: the preparation of the preparation for realizing the production preservation and avoiding the outcrop after the mango disaster weather is prepared as follows:
step one, preparing a compound potassium nitrophenolate aqueous solution A with the mass concentration of 4%.
And step two, preparing a crystalline potassium fulvate aqueous solution B with the mass concentration of 8%.
Step three, mixing the A, B aqueous solutions according to the volume ratio of 0.5:1, and then adding 550ppm brassinolide, 80ppm prodigiosin and 1500ppm spermine according to the concentration to prepare the preparation of the invention.

The formulations formulated in examples 1-3 were tested for effectiveness in areas of the satsuma mango farm, county, where continuous rain, low temperature and hail attacks were encountered:
after the disaster, removing the flower branches with mildewed and rotted flowers or the flower branches which have become smooth sticks in time, providing sufficient space for the growth of the newly drawn flower branches and reducing the sources of diseases. 40 white hanging cards with similar tree vigor are selected to be used as test materials. Respectively randomly selecting 10 cards with red cards, 10 cards with blue cards and 10 cards with yellow cards from 40 cards with white cards. After the preparation is diluted by 1000, 3000 and 5000 times by adopting drinking water, the preparation is sprayed on the leaves of plants of the hang red brand, the blue brand and the yellow brand respectively for the first time. After 10 days, the second foliar spray was repeated. 10 white cards were used as a control group, and no treatment was performed, and the control group was left as natural.
And step two, after the preparation is sprayed, a foliar fertilizer is regularly sprayed in time according to the tree vigor condition, so that the nutrition of the newly growing flowering branch is ensured. Meanwhile, the water and fertilizer management of the root system is enhanced.
TABLE 1 comparison of the effectiveness of the formulation prepared in example 1 with conventional techniques (Ardisia guianensis, age 10 years, data from 2019, 4 and 5 days to 7 and 11 days)
