A simple and easy method for increasing strawberry production

Technical field

The invention relates to the technical field of horticultural crop cultivation, in particular to a simple and easy method for increasing strawberry production.

Background technique

Infrared light refers to the light outside the red light, which is a section of the spectrum with a wavelength from 0.75 to 1000 microns. The far-infrared is long-wave infrared. Recent studies have shown that far-infrared has strong penetration and radiation, and has significant temperature control and resonance effects. It is easily absorbed by objects and converted into internal energy of objects. After the far infrared rays are absorbed by the human body, the water molecules in the body can resonate, activate the water molecules, and enhance the binding force between the molecules, thereby activating biological macromolecules such as proteins and keeping the biological cells at the highest vibration energy level. Due to the resonance effect of biological cells, far-infrared heat energy can be transmitted to the deeper part of the human body, and the generated warm heat can be radiated from the inside to the outside, which can expand the capillaries, promote blood circulation, strengthen the metabolism between various tissues, and increase tissues The regenerative ability of the body can improve the body's immune ability, regulate the abnormal state of mental excitement, and thus play a role in medical care. Far-infrared has achieved very significant effects in human health care, but far-infrared applications in plants are rarely reported, and most of them are the use of far-infrared technology to protect crops and adjust the environment, which directly affects crop production. The impact has not been reported.

Strawberry (Strawberry) is a perennial herbaceous plant in the Rosaceae family. Strawberry produces the largest amount of small berries. Strawberries are bright in color, soft and juicy, rich in vitamin C, iron and other minerals. The main nutritional value of strawberry is the high vitamin C content of strawberry, which contains about 50-150mg per 100g strawberry, which is known as the "Queen of Fruits". In developed countries such as Europe, America and Japan, strawberries have been listed as irreplaceable fruits such as grapes, citrus, and apples. The rich tannins in strawberries have anti-cancer effects, which can prevent chemical carcinogens from attacking the human body. In addition, strawberries are also rich in mineral elements and rich in micronutrients such as riboflavin and carotene, which are deeply loved by people.

In this example, the test material used was strawberry variety peach fumigation, and the test was carried out in a greenhouse, using elevated cultivation.

Example 4

In this example, the test object is an elevated cultivation strawberry in a facility greenhouse, and the strawberry variety is peach fumigation; it was planted on September 20, 2017, processed on November 17, and production was stopped on May 6, 2018; The experiment was carried out in the strawberry greenhouse of Jurong Agricultural Expo Garden. The mature strawberries in this area were cultivated in an elevated manner, and together with other ordinary strawberries in the greenhouse, the plant management, water and fertilizer and other conditions were the same; An easy way to increase the production of strawberries, as shown in the wiring diagram in Figure 2, has three treatment methods. Among them, two far infrared rays are buried in the ground as treatment I, and one line is suspended and the other is buried as treatment II. The two lines that are hanging are marked as treatment III, and the one without far-infrared treatment is marked as the CK group; each group has 4 repeats, each repeat has 10 rows and 2 columns, a total of 20 plants, set between each repeat Isolate the line for isolation.

In this embodiment, the statistics of the growth cycle of strawberries are based on repetition, and the flowering and fruiting phenotypes of three strawberries are used as the standard, and the flowering and fruiting time of different treatment strawberries are counted; in addition, each treatment in the experiment process At least two flower buds that are in the same growth state and the same size are selected for each repetition, and recorded every 7 days until the results are out of date and withered to evaluate the effect of far infrared rays on the growth cycle of strawberries.

In this embodiment, for the statistics of strawberry production, the statistical cycle is from the beginning of the result until the production stop requirement (May 6, 2018) is reached; the production statistics are performed every 3-5 days, and the fruit maturity is selected at 6- 80% (consistent with picking standards in actual production), record with repeat as unit, and analyze strawberry yield with repeat as unit, that is, the yield of 20 strawberries, to evaluate the impact of strawberry yield, the specific results are shown in the table 1 shown.

In this embodiment, for the statistics of strawberry quality, after the results of each treatment are started, the strawberry fruits that are in the ginkgo stage and have the same growth state and fruit shape are selected for labeling and listing after each treatment begins to produce results. 6 8 fruits were harvested uniformly after 7 days, mixed sampling was performed within the repetitions, three sampling repetitions were performed for each repetition, and the samples were stored in liquid nitrogen, and the quality indicators were measured after storage at -70°C; among them, the quality indicators It specifically includes 4 items including VC content, soluble solid content, soluble sugar content and titratable acid content to evaluate the effect of strawberry quality. The specific results are shown in Table 2-5.

Among them, VC content is determined by Fe ion reduction color reaction, soluble solids are determined by portable refractometer, soluble sugar content is determined by anthrone colorimetry, and titratable acid content is determined by acid-base titration.

There was no significant difference in the flowering and fruiting time of strawberries between different treatments, but they were significantly better than the blank control The group was advanced 15-20 days, and the results showed that far-infrared rays can significantly advance the flowering and fruiting of strawberries by 15-20 days.

According to Table 1 (there are 4 repetitions for each treatment in the table, and 20 plants for each repetition. Fruits that meet the production maturity standards are picked and the output is recorded in units of single fruit per plant; the description in the table is within the statistical time , The total yield of 20 plants in a single replicate; the statistical time is from March 24, 2018 to May 6, 2018) and the data in Figure 3 shows that the yield of 20 plants in the three treatment groups is compared with the control group , There was a significant increase in production, 41.81%-63.51%; the yields of treatments I, II, and III were significantly greater than those of the CK group, indicating that the use of far infrared rays had a very significant increase in the yield of strawberries, and the three treatments There was no very significant difference between them; the yield of treatment II was significantly higher than that of treatment I, and there was no significant difference between treatment III and treatment I.
