Rapid high-yield cultivation method for hillside premature Cuiguan pear

Abstract

The invention discloses a rapid high-yield cultivation method for hillside premature Cuiguan pear. The rapid high-yield cultivation method for the hillside premature Cuiguan pear includes the following steps that a hillside with the gradient being 20-30 degrees is selected and flattened, saplings are planted, bud picking is carried out scientifically, nutrient and water management is carried out, the saplings are used as mushroom stalks before budding, twigs are pruned and pulled, 3-4 robust new buds are reserved for every sapling before budding, and other buds are all shorn off; according to flower and fruit management, after field planting of the saplings and before and after blossom in the third year, a worker pays attention to nutrient and water management. The rapid high-yield cultivation method for the hillside premature Cuiguan pear can improve the weight and appearance quality of single fruits of the Cuiguan pear, improves the taste of the Cuiguan pear, increases the soluble solid content in fruits, largely reduces fruit rust generation and damage of diseases and pests, further increases the soluble solid content in fruits, improves the total sugar content and VC content of Cuiguan pear, and reduces the use amount of chemical fertilizer. Through cooperative use of different pest control methods in different stages and an insecticidal lamp, occurrence of various diseases and pests is effectively prevented.

Description

technical field [0001] The invention relates to a fruit and vegetable cultivation technique, in particular to a rapid and high-yield cultivation method for early-maturing Cuiguan pears on hillsides. Background technique [0002] Pear belongs to the genus Pyrus in the family Rosaceae, and there are about 25 varieties, distributed in Asia, Europe, North Africa and other places. There are 14 kinds of origin in China. China is one of the origin centers of pears in the world. The main varieties are divided into Qiuzi pear, white pear, There are four systems of sand pear and foreign pear, but the unit yield lags behind the United States, France and other countries, and the quality of the fruit is far lower than these countries. Pear trees are cultivated in a wide range in China. According to statistics in 1995, the area of ​​pear orchards has grown to about 859.95 10,000 mu, second only to apples and citrus, ranking third in China, and now surpassing citrus, second only to appl...

[0002] Pear belongs to the genus Pyrus in the family Rosaceae, and there are about 25 varieties, distributed in Asia, Europe, North Africa and other places. There are 14 kinds of origin in China. China is one of the origin centers of pears in the world. The main varieties are divided into Qiuzi pear, white pear, There are four systems of sand pear and foreign pear, but the unit yield lags behind the United States, France and other countries, and the quality of the fruit is far lower than these countries. Pear trees are cultivated in a wide range in China. According to statistics in 1995, the area of ​​pear orchards has grown to about 859.95 10,000 mu, second only to apples and citrus, ranking third in China, and now surpassing citrus, second only to apples. Pears are highly adaptable to climate and soil, and among them, Cuiguan pears are known as "June Snow". Cuiguan pear belongs to the sand pear family. It has the functions of relieving cough and phlegm, promoting body fluid and quenching thirst, reducing fever and detoxification, nourishing lungs and helping digestion, detoxifying sores, and alcohol poisoning. The obvious disadvantage of this new variety is that it is easy to form rust spots on the fruit surface. Due to various reasons, hillside terraced fields have not been popularized. The appearance quality of Cuiguan pears produced in China is also generally manifested in: poor fruit uniformity and small fruit , The fruit shape is not correct, the color is uneven, and it is easy to be attacked by diseases and insect pests. The diseases of Cuiguan pear mainly include pear rust, fire blight, scab, and black spot. The main pests are aphids, pear stem bees, leaf rollers, and small food Insects, pear psyllids, and scale insects; in terms of internal quality, they are characterized by thick pulp, slightly more stone cells, low soluble solid content, light flavor, and poor taste. In addition, the current double-layer light-proof bagging It cannot completely solve the rust spots on the peel, and the opaque material used for bagging has affected the peel pigment, especially the chlorophyll content and soluble solids content of Cuiguan pears. In addition, at present, most of the orchards are planted with ordinary chemical fertilizer topdressing, and now The comprehensive ecological gardens in China are generally integrated with planting and breeding, and a large amount of poultry manure cannot be utilized
