Many years of production practice have proved that the Fruit trees of peach, apricot and pear are from the year of planting to the result of the peach three-year apricot four-year pear for five years, and the greenhouse peach tree breaks this convention, the year of colonization, the results of the next year, and can Achieve higher yields and economic benefits. Early spring time to grab early seedlings and extend the growth period of peach trees in order to form the ideal crown in the summer and autumn is the key to winning the next year's high yield. In early spring, the former crops in greenhouses, such as cucumbers and tomatoes, are not yet pulled. Greenhouse seedlings are not easy to handle. Therefore, small arch shelters should be used. In the area around the eastern part of the Yunnan Province, nursery usually begins in late February and early March, and it grows for about 70 days. By mid-May, the height of peach seedlings can grow 60 to 70 cm. This time, they can be planted in greenhouses. This is generally nursery and nursery time. However, there are exceptions. In 1999, Laoting County, Zhongzhuang Wangzhuang Township served as Shaoyan. On April 17th, the nursery was raised. By strengthening management, the nursery exited in early June and the following year he also got a higher output.
First, prepare for seedlings
1. Build a nursery bed and choose a location where the leewards are sunny and have water conservancy conditions. Dig 30 cm deep, 250 cm wide from north to south, rectangular pits with long things, and the length of things depends on the number of nurseries.
2. Prepare 3 nutrients of fully-fertilized organic fertilizer, and no fertile peach trees. No fertility of Daejeon soil was used for spraying omezozole last year. Add 3 kg of compound fertilizer per metre of 3 nutrient soil. Times, stir evenly.
3. The peach seedlings used for cutting anvils, roots, and buds are all semi-finished seedlings that are bud-joined during the late summer and early autumn of last year. The sprouts are cut 1.5 to 2.0 centimeters away. Rootstocks are cut. Oversized trunks of the trunk can be sawn with a hacksaw. The main root of the peach tree is 20 centimeters long, and the lateral root is 8 centimeters thick regardless of its thickness. The overly long part must be cut off. All lateral root cuts should be cut into horseshoe shapes so that the cut plane is parallel to the ground. The purpose of slicing roots is to fit the nutrition bag first, and secondly, to help re-root the roots and form a developed root system. Peach buds on rootstock are all wiped out or cut with a knife. After finishing the root, soak in clean water for 12 to 24 hours, and suck enough water.
Second, nursery main operating procedures
1. A 1 bag (5 g) of strong rooting agent for pharmacy dipping, dissolve with an appropriate amount of alcohol and add 5 kg of water. You can also use 1 bag of Guonaonide (5 grams), add 4 kilograms of water, and soak the roots of 100 peach seedlings. After 5 minutes, remove and put them into the nutrition bag.
2. The nutrition bag with nutrition bag is a plastic bag with a height of 30 cm, a diameter of 20 cm and a thickness of 0.008 cm. The specific method of bagging is: one person supports the mouth of the plastic bag with both hands, and the other person takes the armored nutrient soil. The bag is first filled with 1/3 of the bag height, and the peach seedlings are inserted into the bag, and then the nutrient soil is loaded, and the seedling is paid attention to. The mound is real. More than a dozen small holes should be drilled at the bottom of the bag in order to facilitate permeation and seepage. After loading 100 bags, put the original solution of peach roots, add water to 15 kilograms, and pour 100 bags of peach seedlings in a nutrition bag, and pour 150 grams into each bag. Afterwards, place the bag in the nursery bed and place it tightly, placing 25 bags per meter. Leave 20 centimeters in the nursery bed as a sidewalk.
3. After watering and constructing a nursery bed filled with nutritious bags, immediately water it and spread the nutrition bag over 2 cm. After the water infiltration, a small arch shed was built. The soil around the membrane was compacted with clay and the grass was covered with cold at night.
4. Manage the curtains during the day and cover the curtains at night. The daytime air temperature is controlled between 25 and 28°C. The maximum temperature does not exceed 30°C, nighttime is 5°C to 8°C, and the minimum temperature is not lower than 0°C. The maximum temperature does not exceed 24°C. Pay attention to eradicate new hairy peach buds and control pests such as aphids and leafhoppers at any time. From mid-May to mid-June, seedling heights of 60 to 70 cm can be planted in the greenhouse.
