Planting technique of Zaosuhong Pear

Early crisp red is a new type of fruit which is popular in the market in recent years, its peel is red, it is easy to distinguish from ordinary pears, and its nutritional value is very high. After facing the market every year, it will be in short supply. So now many people see its economic prospects, so they want to try to grow it.

Planting technique of Zaosuhong Pear

Dig holes and plant. It is suitable that the depth and width of the planting hole is about 1m, the bottom of the hole is covered with organic matter and return to the soil to about 50cm, then apply 25~50kg organic fertilizer, high-quality farm manure is better, combined with pear special organic fertilizer, the application rate is 1000~3500kghm-2, and add calcium magnesium phosphate fertilizer 1kg in acid soil or calcium superphosphate 1kg in alkaline soil, cover soil to settle, can be planted. When planting, the method of "one lift, two steps and three burying soil" is adopted to straighten out and distribute the root system evenly, ensure that the root system is intact, backfill the soil to the root neck, ensure that the soil at the root neck is higher than the surrounding ground 10~20cm, and immediately irrigate the water after planting, so as to ensure the fixation and water supply of the root system in the soil, and finally cover with a layer of fine soil or plastic film within the 1m2 range of the hole.

Water Management of Zaosuhong Pear

1. Irrigation. Zaosuhong pear has five water demand periods (sprout water, flowering water, fruit water, pre-harvest water and overwintering water) in a year, and each irrigation amount is different, and the general water content should be kept at 50%-80% of the maximum field capacity. Irrigation periods are carried out in spring, early May, mid-June, mid-August, early November and timely irrigation combined with soil drought. Water-saving irrigation methods such as drip irrigation or sprinkler irrigation can be used for irrigation, and grass or film mulching can also be used around the tree plate to achieve the effect of moisturizing and water storage.

2. Drainage. The orchard with high groundwater level and heavy soil should avoid stagnant water to avoid root damage due to poor air permeability, so the drainage ditch of 30~40cm must be opened in the orchard. After too much watering or heavy rain, the stagnant water should be removed as soon as possible.

Common insect pests and Control methods of Zaosuhong Pear

The main results are as follows: 1. Dendrolimus punctatus is the main leaf-eating pest of pear trees. Larvae damage flower buds, buds and leaves twice a year, usually from March to April and from August to September. The suitable period for control is when the overwintering larvae are stung, that is, from pear flower buds to inflorescence separation. The commonly used agents are: 50% parathion emulsion 1500 times, 50% phoxim emulsion 1000 times, 50% fenitrothion emulsion 1000 times, 50% malathion emulsion 1000 times, 50% dichlorvos emulsion 1000 times and 20% fenvalerate emulsion 3000 times.

2. Pear Shifeng (commonly known as flower drill, white drill worm) is only harmful to pear trees. The adults lay eggs in the calyx, and the larvae initially graze in the inner circle at the base of the calyx, and then eat into the core of the fruit after blackening, causing the young fruit to dry up and fall off. The larvae climb out before falling fruit and turn to harm other young fruits. The insect produces a generation a year and overwinters with mature larvae as cocoons in the soil. The adults Eclosion and lay eggs from late April to early May. The peak spawning period is when the pear inflorescence is separated to the petal is budding, and the larvae are damaged by fruit decay in the middle and last ten days of May.

The false death of adults can be used to pick up sheets under the canopy, vibrate adults to kill them, or artificially remove egg-bearing flowers and young fruits during the spawning period. When adults are unearthed 10 to 15 days before pear blossom, ground spray is carried out with 300 times of 25% parathion, 300 times of 25% phoxim or 600 times of 40.7% Lesben EC, with emphasis on 1 meter around the trunk.

Harvest time of early crisp red pear

The main results are as follows: 1. The harvest time is determined comprehensively according to fruit maturity, use and market demand. The harvest maturity should be 890%. Long-distance sales or storage should be harvested at about 80% maturity, and close sales should be harvested at about 90% maturity.

2. Pre-harvest preparation. Organize the harvester, who shall cut off his fingernails or wear gloves to pick. Refurbish grading sites, tools, containers and machinery.

3. Harvest and storage. If you harvest in batches, the big fruit will be picked first. Pick and place lightly to prevent bruising and abrasion of the fruit. Timely transport into the grading site to avoid extrusion and other mechanical damage, classification after pre-cooling into the warehouse.

Early crisp red growth conditions are very wide, except for very cold places, in most areas where I have been able to grow it. And after a bumper harvest, the fruit is very resistant to storage, whether the fruit is eaten raw or cooked, or canned, is a very good choice, so pay attention to the cultivation, the return in the later period is still very considerable.
