Description
Technical Field
The invention relates to the technical field of plum planting, in particular to a regulation and control planting method of high-quality plums.
Background
The plum belongs to the Rosaceae (Rosaceae) plum (Prunus L.) and has wide distribution range and large cultivation area in China, and belongs to one of the main fruit tree types with high yield. The plum is a common fruit in daily life, tastes sweet and sour, contains rich carbohydrate, can be eaten fresh, is processed deeply, and has high market demand, wherein the demand on the quality and the fruits of the fresh plum is high.
The plum tree planting has high requirements on moisture and nutrition, strong temperature adaptability and no special requirements on soil, so that the plum tree planting has wide distribution range in China. However, due to unscientific planting of fruit growers, such as unreasonable fertilization and poor watering management, the disease resistance of plum trees is very easy to be poor, diseases such as red spot disease, bacterial perforation disease and the like are easy to occur, the fruit produced is serious in fruit drop, low in yield and poor in quality, besides, the nutrient absorption of the plum trees is too much due to the improper water and fertilizer, the content of internal pectin is high, cell walls are broken after the pectin is degraded, and the skin and the inner core of the fruit are cracked. If plums generate the phenomenon of cracking nuclei and pectin and fructose are separated from the inner part of the plums close to the kernels, transparent crystals can be formed at the cracking nuclei of the plums to influence the taste, but the core cracking phenomenon is different from the normal boneless plum variety, the boneless plums only can be separated from the kernels, and odorless transparent inner crystals are not generated to influence the taste. In addition, when the plum is picked, low-temperature storage and transportation are adopted, fructose and pectin in the thawed plum are further separated out, the phenomena of internal cracking and crystallization are aggravated, the quality of the plum is reduced again, and the economic benefit of fruit growers is reduced. Therefore, the invention aims to provide a regulating planting method of high-quality plums, which solves the phenomena of nuclear fission and internal crystallization in the planting process of the plums.
Disclosure of Invention
In view of the above, the invention aims to provide a regulating and planting method for high-quality plums, which solves the internal crystallization phenomenon after the core cracking in the plum planting process and improves the plum quality.
A regulation and control planting method of high-quality plums comprises the following steps:
(1) planting: selecting a land block with a deep soil layer and drainage ditches to plant the plum trees;
(2) trimming: pruning the fruit trees in the full bearing period;
(3) topdressing in flowering phase: topdressing with urea or calcium superphosphate before and after blooming;
(4) thinning fruits: thinning the fruits when the fruits grow to the size of the soybean grains within 20-30 days after the flowers bloom;
(5) topdressing: applying a phosphorus-potassium fertilizer for topdressing in the fruit hard core period;
(6) regulating and controlling: regulating by using a regulating agent 65-70 days after the flowering, and applying the regulating agent to the lateral roots;
(7) picking: the plum fruits are picked after the fruits are nine ripe.
Further, when the fruit trees are pruned in the full bearing period, branches with the thickness less than 0.6cm are thinned and removed in winter, branch pulling and angle expanding are carried out in summer, auxiliary cultivation branches are pulled to 70-80 degrees, the base angle of main branches is pulled to 50-60 degrees, and new tips are simultaneously pinched.
Further, the topdressing in the flowering phase comprises a pre-flowering topdressing and a post-flowering topdressing, wherein the pre-flowering topdressing is applied 2 weeks before flower germination, 0.2-0.5kg of urea is applied to each plant, the post-flowering topdressing is applied 1-2 weeks after flowers sprout, and 0.5-0.6kg of calcium superphosphate is applied to each plant.
Further, the fertilizer is characterized in that the additional fertilizer is applied to the fruits in the hard core period, and 0.5-1kg of phosphorus-potassium fertilizer is applied to each plant.
Further, the regulating agent comprises the following raw materials:
dried suaeda salsa, betaine, sodium phosphate, boric acid, seaweed gel, wormcast and salicylic acid.
Further, the regulating agent comprises the following raw materials in parts by mass: 10-20 parts of dried suaeda salsa, 2-5 parts of betaine, 0.8-1.2 parts of sodium phosphate, 1-2 parts of boric acid, 20-40 parts of seaweed gel, 40-50 parts of wormcast and 1-2 parts of salicylic acid.
The polygalacturonase can participate in the degradation of pectin, so that the starting of the polygalacturonase in plums is closely related to the pectin content, when the polygalacturonase is inhibited by activity, the pectin degradation is slowed down, the cell wall structure of fruits is well maintained, the pectin in plums is prevented from being separated out, internal crystallization is formed, and the taste is reduced.
Further, cleaning dried suaeda salsa, drying, crushing and sieving, adding the dried suaeda salsa into hot water at 30-40 ℃, soaking for 12-24h, adding seaweed gel, sodium phosphate and betaine, stirring uniformly, heating to 80-85 ℃, reacting for 10-20min, placing in a shade, storing for 1-2 days, stirring uniformly again, and adding boric acid, salicylic acid and wormcast to obtain the regulator.
Further, the use method of the regulating agent comprises the following steps: avoiding the main root of the plum tree, selecting 1-2 lateral roots to cut off, and applying the regulating agent to the cut-off lateral roots.
The method comprises the steps of decomposing suaeda salsa and seaweed gel under the conditions of sodium phosphate and betaine, then digesting and activating by boric acid and salicylic acid to obtain a regulating agent containing plant growth regulator, various amino acids and trace elements, applying the regulating agent to plum trees to promote nutrient accumulation of the plum trees and accelerate fruit expansion to obtain high-quality plums. And residual salicylic acid and boric acid enter the tree body through the side root wound of the plum tree to cause infection artifacts, polygalacturonase inhibitor protein is activated to prevent pectin from being degraded and separated out in the maturation process, and meanwhile, the polygalacturonase inhibitor protein is combined with the polygalacturonase of the plum tree to activate a defense system in a plant body to resist invasion of pathogenic fungi from the dug-off side root and prevent insect damage.
Furthermore, the dosage of the regulating agent is 0.2-1kg per plant.
Furthermore, the regulation and control planting method is suitable for the varieties of the green crisp plums and the crisp red plums.
Has the advantages that:
the regulator is used for regulating the internal hormones of the fruits in the planting process, so that the structural integrity of the cell wall of the fruits is maintained, the pectin is prevented from being separated out to form internal crystals, the taste of the plums is reduced, and the quality of the plums is improved. The regulator can also supplement nutrient substances such as nitrogen, phosphorus and potassium, amino acids, trace elements, plant growth regulators and the like to the plum trees so as to improve the weight of a single fruit and the yield of a single plant.

(7) picking: picking the plum fruits after the plum fruits are nine ripe;
during the planting period, proper amount of water is timely watered according to the rainfall.
Firstly, a regulation and control test:
and (3) independently opening up a test area in the base, wherein the variety in the test area is green plum, the tree age is 5 years, the tree form is open heart-shaped, and the row spacing is 2.5 multiplied by 4 m. The land in the test area is uniform, the tree ages, tree vigor and flowering phases of the plum trees are basically consistent, 30 plum trees are selected and divided into 10 groups, each group comprises 3 plum trees, and the plum trees are not interfered with each other during operations such as fertilization, watering and the like. The average yield of single trees in the first two years in the test area is about 32kg, and the weight of single fruit is about 20 g.
The plum trees in the test area are planted according to the method of the embodiment 2, the watering management and the pest control are carried out by the same level and method except that the fertilizer application and the selection of the regulating agent are different, the regulating agents prepared in the experiment groups 1-3 and the comparison groups 1-6 are respectively applied to the regulating agent, and one group is selected as a blank control.
The blank control group planting method comprises the following steps:
(1) planting: selecting a land block with a deep soil layer and drainage ditches to plant the plum trees;
(2) trimming: cutting fruit trees in the full bearing period in winter and reducing the fruit trees in summer, thinning branches with the thickness of less than 0.6cm in winter, reducing ineffective branches, drawing branches and expanding angles in summer, drawing auxiliary cultivating branches to 70-80 degrees, drawing main branch base angles to 50-60 degrees, and simultaneously pinching new tips;
(3) topdressing in flowering phase: applying the topdressing before flowers 2 weeks before flowers sprout, applying 0.3kg of urea to each plant, applying the topdressing after flowers 2 weeks after flowers, and applying 0.5kg of calcium superphosphate to each plant;
(4) thinning fruits: thinning the fruits within 20-30 days after the flowers grow to the size of soybean grains, and reserving one fruit at intervals of 5-8 cm;
(5) topdressing: applying a phosphorus-potassium fertilizer and additional fertilizer in the fruit hard core period, and applying 1.2kg of phosphorus-potassium fertilizer to each plant;
(6) picking: picking the plum fruits after the plum fruits are nine ripe;
during the planting period, proper amount of water is timely watered according to the rainfall.
In the late middle and late 6 months, the plums are harvested and stored individually after reaching nine ripeness groups, the yield of each plant is recorded, 300 fruits are randomly selected for weighing, the average weight of each fruit is calculated, the average number of crystallized fruits with pectin precipitated crystals in each 100 fruits is recorded, and the recorded data are shown in table 2:
TABLE 2
From the data in table 2, it can be seen that:
1. the blank group is planted by a conventional planting method, the weight difference between the single plant and the single fruit in the past year is not large, but the yield of the single plant is reduced and the weight of the single fruit is reduced compared with the blank group in the comparison group 3-6, because the dosage of the phosphorus and potassium fertilizer applied in the hard core period of the fruit needs to be increased if no regulating agent is applied in the planting process of the conventional method, the dosage of the phosphorus and potassium fertilizer is reduced when the regulating agent is not in place in the comparison group 3-6, and the quality of the fruit is reduced. In addition, although the experimental group digs off the lateral roots, the growth vigor of the plum tree is not obviously different from that of the blank group and the root rot phenomenon does not occur.
2. Compared with the blank group, the single fruit weight and the single plant yield of the experimental groups 1 to 3 are increased by a certain amount, but the number of the crystallized fruits with pectin precipitated crystals in 100 fruits is obviously reduced, because the regulation and control of the regulation and control agent in the later period of the fruits not only supplements nutrition, but also regulates the pectin content in the fruits, better maintains the cell wall structure of the fruit cells, prevents the pectin in the plums from being precipitated and forms internal crystals.
3. Compared with the comparative group, the experimental group 1 has the greatest difference between the single fruit weight and the single plant yield of the comparative group 5 and the experimental group 1, and the difference respectively reaches 11.9g and 14kg, because the comparative group 5 only adds the suaeda glauca, the wormcast and the salicylic acid, and the plum trees can absorb less nutrients after the suaeda glauca is not treated, so that the fruits can not accumulate the nutrients in the expansion period. In comparison with the experimental group 1, the decomposition of suaeda salsa and seaweed gel without adding sodium phosphate resulted in limited absorption of the internal nutrition of suaeda salsa and seaweed gel by the plum trees, resulting in lower yield and lower weight of single fruit. Compared with the experimental group 1, the comparative examples 4 and 6 have the advantages that polygalacturonase inhibitor protein cannot be activated without adding salicylic acid and boric acid, so that pectin is prevented from being degraded and separated out in the maturation process, the number of crystallized fruits is increased, and the quality of the fruits is reduced. The comparison group 1 is not added with the dried suaeda salsa, so that part of nutrient substances are reduced in the process of decomposition and digestion, and the whole yield of the fruit tree is slightly reduced. The comparative group 2 was not added with betaine, which in cooperation with sodium phosphate promoted the digestion process to promote the release of nutrients of dried suaeda glauca and seaweed gel. Therefore, the regulating agent prepared by the invention can obviously increase the yield of the plum, improve the quality and especially obviously reduce the internal crystallization probability of the plum fruit.
Although the present invention has been described in detail with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted without departing from the spirit and scope of the invention as defined in the appended claims. The techniques, shapes, and configurations not described in detail in the present invention are all known techniques.
