High-yielding Cultivation of Strawberry in Greenhouse
The greenhouse strawberry cultivation is relatively easy and the economic benefits are high. The development of the whole country is very fast. Based on many years of experience, we now introduce high-yield practical cultivation techniques as follows.
I. Variety selection
The outstanding breed is Baozao Zaosheng. Its characteristics are as follows: First, the flesh is tender, the sweetness is intense, and the quality is excellent. It has obvious competitive advantages in the market, its price is higher than other varieties; Second, shallow dormancy is suitable. It is cultivated in the greenhouse for the purpose of the morning market.
Second, the greenhouse cultivation process
1. Establishment of nursery nursery Planting mother plants in early April, the mother plants were planted with open-season stem shoots planted in the previous year, and 700 to 800 plants were planted per acre. In stalk processing, a female plant can reproduce 70 to 80 robust seedlings. The criteria for strong seedlings are thicker than 1 cm roots, 3 cm to 5 cm in length, 3 to 5 standard leaves, and robust plants.
2. Planting time is from early September to early October. 25 days before planting, 5,000 kg of high-quality organic manure per acre, 100 kg to 150 kg of biological potash, 30 cm of deep soil, 10 cm to 15 cm of ridge height, 40 cm to 50 cm of ridge width, The ridge spacing is 15 centimeters to 20 centimeters, north and south ridges, sunny, bactericidal insecticide, to prepare for planting.
3. The greenhouse shed is generally east-west, with a length of 50 to 60 meters, a width of 7 to 8 meters, and a height of 2.5 to 3 meters. The time for picking the canopy is determined according to the time when the fruit is picked. Usually Baozao blooms 1 month after the early growth and shed, and after 1 month of flowering, the fruit begins to ripen. The harvest period is about 1 month. According to the requirement of cooling capacity, the temperature of the shed can be increased from mid-October to mid-November.
4 temperature management bud to early flowering, suitable temperature during the day is 20 °C ~ 30 °C; harvesting period of 8 °C or more; daytime temperature in the shed to high ventilation, such as the outside temperature is too low, should put the top wind, stroke, can not put Bottom wind.
5. Flowering management optimum flowering temperature during the day 20 °C ~ 25 °C, night 5 °C ~ 6 °C, the minimum temperature can not be less than 3 °C; flowering shed optimum humidity of 50% ~ 60%, if too large, timely ventilation Wet; no watering, no watering during flowering; no fertilization or spraying during flowering period to prevent flowering victims; flowering bees should be used for pollination.
In addition, it is necessary to fertilize water and prevent diseases and pests in order to ensure the healthy growth of strawberries.
Work Systems of the Testing Room
1. Keep the testing room clean and quiet, and pay attention to electrical safety.
2. Before testing, metal and communication equipment on the tested person`s body should be removed for proper placement.
3. Those who wear pacemakers are not appropriate for testing.
4. During work, inspect whether the power supply and the testing system are in a good using condition.
5. In the testing process, the operational regulation must be strictly observed.
6. Out of work, cut off the power supply and clear up the used equipment and the tester to make them be in a good standby condition.
The Quantum Magnetic Resonance Analyzer replaces the need for ultrasonic, nuclear magnetic resonance or radiography for various health related conditions. Holding sensors in your palm simply, health data will be collected within minutes from various body systems. The magnetic resonance analyzer offers new advantages in the field of material analysis. It has been shown that the applicability of such an analyzer exceeds the range of tissue analysis and other medical applications. The magnetic resonance analyzer measures the degree and type of response of a matter under test, and by comparison with reference matter it assists in recognizing deviations from the desired response. The software interface has updated high technology that the operation is more convenient and faster. The main future is 2 languages in software in one machine, both with English and another language.
