First, the planting time of Bigen fruit

The sowing date of Bigen fruit in the north is April 5-10, and can be brought forward in the south.

The stratification temperature is 2 ℃-3 ℃ and the time is 60-90 days. The seeding density is generally 50 cm between rows and 30 cm between plants, about 4500 plants per mu, and the sowing depth is 5-7 cm.

Second, the planting method of Bigen fruit

1. Soil preparation and fertilization: the green root fruit planting should choose the land with deep soil layer, loose, sufficient water source and leeward to the sun, the plant row spacing is 4 × 5 m-7 × 8 m, the planting hole is required to be 1-1.5 m in diameter and 1-1.2 m deep, and the topsoil and core soil are open, first put a layer of straw at the bottom of the pit, cover the topsoil to 20 cm, put in 50 kg of organic fertilizer, 20 g of methamphetamine powder, 500 g of superphosphate, and mix well with the soil.

two。 Painting white (lime) on the trunk of a big tree can prevent the occurrence of freezing injury of the trunk.

3. Pruning: the early pruning of the green root fruit should be light, leave more main branches appropriately, make it bear fruit early, make the inner chamber of the crown ventilated and transparent, the upper branches of the early crown should be retained as far as possible, and the lower part of the crown can be thinned step by step. If necessary, the overdense branches can be sawed off, and the saw must be cut flat and coated with protective agent to prevent decay. After entering the aging period, all the parts above the regeneration branches of the crown can be sawed off, the germinated regeneration branches can be cultivated, and the dead part of the main branch of the aging crown can be cut off. at the same time of pruning and renewal, it is best to combine deep turning and fertilization.

4. Intermediate ploughing and weeding: soybeans, corn and Atractylodes macrocephala macrocephala can be intercropped within 1-3 years of the construction of the Bigen orchard. In the process of intercropping, the garden should be mid-ploughed and weeded, while appropriate amounts of organic fertilizers such as coke ash, cake fertilizer, barnyard manure and other organic fertilizers should be applied. In addition, weeds, shrubs, thorns and vines will be cut off 1-2 times every year to cover the woodland, and the mulch will be ploughed into the soil in winter to increase soil fertility.

5. Fertilization and fruit protection: before the Bigen fruit germinates in spring, about 30 kg of urea is applied per mu, 80 kg of special fertilizer for fruit trees is applied during the fruit expansion period, and 3000 kg of base fertilizer is applied in autumn. After entering the fruiting period, applying more fertilizer according to the results can be combined with spraying fertilizer once every 15 days or so, spraying 0.3% urea in the early and late growth stages, 0.3% potassium dihydrogen phosphate from June to July, watering enough overwintering water and sprouting water in winter, timely drainage and waterlogging prevention in the rainy season, fertilizing the fruiting trees twice a year, opening shooting ditches along the tree plate in February, applying 20 kg of corn stalks per plant and 5 kg of dung. In July, the main fertilizer was ternary compound fertilizer, 0.2 kg per square meter.

6. Pest control: the main diseases and insect pests of Bigen fruit are hickory branch blight, longicorn beetle, green thorn moth, coffee bark moth, etc., focus on orchard pest control in winter, timely prevention and control according to the occurrence of diseases and insect pests. At the same time, strengthen the tree potential, prevent branch damage, spray carbendazim or chlorothalonil and other agents during the disease period.

The above introduces the planting time and method of Bigen fruit. I hope it can be helpful to you!
