Cherry cultivation in our country, which has been growing for 3,000 years to date, has been expanding in recent years with the development of facilities agriculture, owing to its low input and high yield characteristics. So, what about the cherries? The following country song will be discussed with you。
I. Artificial pollination to increase sit-in rates
1. The high temperatures and poor ventilation in the cherries shed in the sheds make bouquets particularly important for utilisation. Artificial pollination, which is the main method of pollination, is more efficient and allows cherry trees to produce more fruit。
2. Cherry pollen for artificial pollination in large sheds, preferably collected on open cherries trees, starting at the beginning of the cherries with two to three consecutive pollinations。
3. Artificial pollination may be used to extract pollen from a brush or rubber head, to place it on the head of a flower, to perform it, to pollinate it with a pollinator, and to place it manually for the first 1-2 days of flowering. The pollination can be facilitated by pollination with a stick-based pollinator, with a wooden stick or pole on top, with plastics about 50 cm in length, outsourcing a clean gauze, touching different flowers and tumbling between cherry blossoms。
Ii. Alteration of sheds to regulate temperature
The poor ventilation in the cherries sheds and the critical regulation of temperature can lead to freezing if control is not reasonable, resulting in low sit-in rates and decay of fruit and leaves。
1. The plastic shed must be at an altitude of approximately 2. 5 m, which would facilitate both the operation of staff and the ventilation of the shed。
2. Appropriate provision for ventilation windows and vents, working doors and venting windows in each of the east-west walls, or installation of wind fans for temperature and humidity regulation in the follow-up shed. The ventilation window of the operating door should be fully opened within 3-4 days, with subsequent gradual closure of the operating door and the ventilation window, gradual covering of the straw curtains 10 days later at night, at 10-17 p. M. Per day when the temperature rises to 16°c, after 17 p. M. Closing of the ventilation window and covering of the straw curtains, opening of the straw curtains every day after the sun comes out, until the tree canopy closes to the flower, with plastic film covering to control the temperature within the tree canopy。
Iii. Increased application of decomposition organic fertilizers and soil improvement
1. The high organic content of the soil results in soil decomposition and ventilation and high cherry production. Most soils have organic content of about 1 per cent, which is lower than the need for cherry growth. Increased application of organic fertilizers is therefore necessary to improve soil and to improve soil air retention。
Increased soil organicity has also contributed to increased soil microbial activity. The activities of micro-organisms have eased the soil and produced substances that promote root systems and are beneficial to their growth. If the soil is condensed, it is directed to the carbon dioxide required for plant growth, such as by microbacterizers, and the heat resistance to disease-resistant spores, enzymes, organics and inorganic nutrients can increase soil porosity by more than one-fold in the 20-centimetre farming layer。
Iv. Rational watering to control soil moisture
1. Cherry shed space is relatively small and airy, and when ventilation is not observed, the air flow will be relatively stable, evaporating at higher temperatures during the day, and the shed environment is relatively closed and difficult to keep up with the external air, often resulting in high indoor humidity。
2. The effects of traditional watering on soil erosion and pressure are strong, and the air in the soil is squeezed out by heavy water flooding, and the corrosive structure of the soil is destroyed to the detriment of soil conservation. Following the watering, the surface layer of the soil is reduced in its permeability, requiring the cultivation of pine soil, breaking the surface layer of the soil and restoring the permeability of the soil。
3. Dripping has the effect of protecting soil. The drip irrigation is different from the floodwater, and it is slowly immersed in the soil. In areas where drip irrigation has been widespread for many years, it is widely reflected that the soil in the sheds where drip irrigation is used is more loose and air-transmitting。
V. Orthopaedic trimmed and luminous
1. Mainly, the vertical branches on the back of the main branch, the competition branches on the main branch and the long branches on the main branch, as well as the long branches of the long fruit, which are too dense for one year, are being cut back to the weak branches. 2. The angles on the larvae and individual trees of the result of the replanting and the main branches of the poorly placed branches are to be formed by pull: mainly in the form of natural fun or free-swipe trees. The tree is small, the cherry tree is flourishing, the tree is standing up and is not open。
3. A parallel stretching method is used either in spring fluid flow or after autumn august-september. The opening angle is about 60 degrees to ease the tree position and increase the amount of flowers. In order to foster the separation of branches and to contribute to the separation of buds, the branches must be short-cut, new branches must be promoted and tree canopy expanded before spring springs. During the summer, new steps are taken, and the top is cut to 10 centimetres when the main branch is extended and the central leadership branch grows to more than 30 centimetres, while the rest of the branches and the back branch are left around 8 centimetres to be severed. A strong branch can be re-circled, and a strong branch on its back can be continually driven to form a group of results。
It is common for large sheds to grow cherries with poor air intake, which, if not properly disposed of, can reduce production or yield losses, and increase productivity efficiency if the above points are followed. You think so? Click on happy year
