Approval number: Guangyao Tao (20 18)370008.

Suitable planting area of Huangjinmi No.4

Jinjin 4 is a local variety that has been widely popularized in production. It is suitable for planting in Shandong peach producing area after thawing in spring and before germination or after defoliation in autumn and before freezing.

Yield per mu of Huangjinmi No.4

During the growth period of 1, the yield per mu of Jinjin 4 was 2627 kg, which was 5.438+0% higher than that of the control Jinyuan. In the second growth cycle, the yield per mu was 2693 kg, which was 2.90% higher than that of the control Jinyuan.

Characteristics of Huangjinmi No.4

① Fruit characteristics

Jinjin No.4 peach is big, with an average fruit weight of 287 grams, the maximum fruit weight of 573 grams, fruit shape index of 0.88, hard and brittle fruit, pulp hardness of 7.4 kg/cm2, and good storage and transportation resistance.

② Taste

High sugar content, soluble solids 14.5%, crisp and sweet taste, titratable acid content of 0.26%, vitamin C content of pulp of 6.0 mg/100 g, golden yellow meat with antioxidants.

③ Characteristics of planting management

After the fruit is bagged, the fruit surface is golden yellow. The fruit development period is about 1 10 days. Strong resistance to perforation, brown rot, scab and anthracnose.

Jinhuijin 4 peach variety has strong self-pollination ability, but the stigma comes out first when some flowers are not in bloom, so artificial pollination can be used to improve the fruit setting rate in production. Growers need to bag in the young fruit period, otherwise the fruit will be easily colored on the sunny side and will not appear golden yellow.

Huangjinmi No.4 peach 1 cultivation points

It can be planted after thawing in spring and before germination, or after defoliation in autumn and before freezing.

2. Cultivation methods

This variety is late-maturing and suitable for open-air cultivation. Ridge cultivation is adopted.

3. Planting density

According to different terrain and soil conditions, the plant spacing of flat peach orchard is 1.5 ~ 2m× 4m, and that of mountain peach orchard is 3m× 4m.

4. Fertilizer and water management

Dig deep into the soil and apply more organic fertilizer before planting; Irrigate the border surface with 1 flood in time after planting, and cover it with plastic film to preserve moisture, so as to improve the survival rate; After survival, water it in time to promote growth.

After entering the fruiting period, water should be guaranteed at least four times a year: germinated water, hard core water, swollen water and frozen water, and water should be replenished in time according to water demand in other periods.

In the early growth stage of young trees, nitrogen and phosphorus are mainly used to promote growth. In the late growth stage, phosphorus and potassium fertilizers were mainly used to promote the maturity of branches.

After entering the fruiting period, the amount of nitrogen fertilizer should be appropriately reduced, and phosphorus and potassium fertilizers, bio-organic fertilizers and medium and trace element fertilizers should be applied to promote flowering and fruiting and improve fruit quality.

5, pest control

Carry out the plant protection policy of "prevention first, comprehensive management", scientifically use chemical control technology, and effectively control pests and diseases.

6. Flower and fruit management

It blooms on April 3, with a large amount of pollen and strong self-pollination ability, and the fruit should be thinned in time after physiological fruit drop.

Generally, the fruit is thinned in May1March-May 16, bagged on May 25-30, and ripened on August 2. The fruits are harvested in three batches, once every 5 to 7 days. Harvest in bags without coloring.

7, plastic pruning

Taoyuan, the modern cultivation mode of flat land, adopts high "Y" shape shaping, which saves labor and effort, simplifies pruning technology and is easy to learn. Peach orchards in mountainous areas adopt improved kaixin (Sanli) plastic surgery, which has long service life and good yield.
