Golden fruit flesh is golden yellow, like a halo formed by sunlight; In taste, the slightly sour taste of common kiwifruit is completely removed, and the taste is mixed with the tastes of cantaloupe, peach and citrus, showing a unique sweetness.
Brief introduction of planting techniques of organic kiwifruit
First, site selection, garden construction and scientific planting.
Kiwifruit Orchard, a green food, should be located in slightly acidic soil with loose soil at an altitude of 300- 1200m, where the air, soil and water are free from pollution. The park is built on a gentle slope below 25 degrees, with convenient irrigation and drainage and good traffic conditions.
At the initial stage of the garden construction, planting ditches with a width of 1m and a depth of 60-80 cm were made in rows of 3 meters. Or dig a big hole of 1 m in Fiona Fang, with a spacing of 4× 2m, apply sufficient organic fertilizer, and fill it with ripe soil for later use. Where conditions permit, the whole garden can be turned deep, which is beneficial to the root growth of kiwifruit in the later stage. In recent years, Pujiang Kiwifruit Orchard generally adopts the method of deep turning of the whole garden, with a depth of 80 cm.
Scientific seed selection and scientific planting. Planting should choose excellent varieties with good production performance, good quality and can connect with the market; Red heart and yellow meat are preferred, with tender texture, sweet taste and high sugar content, such as Hongyang, Jin Yan, Jinguo, Jintao and Cui Xiang. The patented variety Donghong Kiwifruit introduced by Lenovo Group has achieved good performance in small-scale planting in Pujiang. The single fruit weight is increased by 20 grams compared with the original red heart fruit, and the yield per mu is greatly increased compared with Hongyang Kiwifruit. The disease resistance, high yield and fruit storage and transportation resistance are greatly improved compared with Hongyang kiwifruit, and there will be a good market response in the next few years. Selecte that first-class and second-class seedlings that meet the national seedling grade standard. Before planting, apply plantar fertilizer. When planting, make the roots of seedlings stretch, fill in a small amount of fine soil, gently lift the seedlings, fill the soil and tamp it, and then pour enough water to stabilize the roots. At the same time, insert the drawbar.

Second, deep ploughing and fertilization
Deep ploughing and fertilization is a comprehensive technical measure integrating soil deep ploughing and improvement, base fertilizer application and root pruning, which is an inevitable requirement for green food production. In the past, deep tillage was completely separated from base fertilizer application, which caused problems such as high labor intensity, poor fertilization effect and weak growth.
(1) Deep turn
Deep tillage is the only soil tillage measure in kiwifruit orchard all year round. No matter whether the soil is hardened or sticky, it should be deeply cultivated and filled with organic fertilizer and quick-acting fertilizer. There are two ways of deep turning: reaming and staggered deep turning. Hole enlargement is to expand the original planting ditch year after year until all the rows are turned over. This is a way to turn over the nursery deeply. Staggered deep turning is once every other line every year, and four years is a cycle.
The best time for deep ploughing is to combine fertilization immediately after fruit picking and before defoliation. If the labor force is insufficient, deep ploughing can be completed before freezing, and it is prohibited during the growing period. The range of deep tillage is often based on the distribution layer of the main root system. Dig ditches with a depth of 40-50 cm and a width of 30-50 cm, and change the direction and position of digging ditches alternately every other year, and gradually extend from the trunk. The method of deep tillage is: first shovel the surface layer of weeds to one side, determine the scope of ditching, put the dug 20 cm deep topsoil and weed layer together, and put the subsoil on the other side. The root system in the ditching area must be cut off along the ditch edge. If the root system is not met, it means that the determined ditching range is too far from the trunk and needs to be determined again. After a ditch is dug, it is necessary to backfill enough base fertilizer in layers in time, so as not to let the roots catch cold and affect the regeneration and growth of the roots.
(2) Fertilization
Base fertilizer is a kind of basic fertilizer that can supply various nutrients to trees for a long time. It is mainly composed of manure, compost, green manure, crop straw, biogas residue, livestock manure, compost, leaf weeds and other organic fertilizers. , supplemented by plant ash, compound fertilizer and bio-organic fertilizer. The application amount of base fertilizer accounts for 80-90% of the total annual fertilization amount, and the ratio of nitrogen, phosphorus, potassium and magnesium is 10: 6-8: 10: 0.5. Add zinc fertilizer and boron appropriately, and prohibit the use of chloride and urea. According to local experience, 50-60 kg farmyard manure was applied to each mature kiwifruit orchard, and the mixed application rates of nitrogen, phosphorus and potassium were 1.5, 1.0 and 1.5 kg respectively. According to the fertilizer requirement of 100 kg fruit production, in recent years, 50 kg of decomposed organic fertilizer and 0.5-0.8 kg of compound fertilizer were applied to each 2-4 year old tree. Adult trees are applied with 50-75kg of decomposed organic fertilizer and mixed with 1 .5kg of compound fertilizer or1kg of ternary compound fertilizer+0.5kg of bio-organic fertilizer. Fertilization method: Calculate the fertilization amount according to the total number of plants in each row in the deep tillage fertilization ditch and divide it into two halves. First, apply organic fertilizer and compound fertilizer in the ditch, fill the top soil, then apply the other half of organic fertilizer and compound fertilizer, fill the bottom soil to form the shape of tile back, and fill it with water or biogas slurry. First, pay attention to timely fertilization and backfilling during deep ploughing; Second, it should be carried out when the temperature is high after fruit picking in autumn, which is beneficial to fertilizer decay and root growth.

What are the characteristics of kiwifruit varieties?
Originated in New Zealand, it is named for its yellow flesh after ripening. Huang Jinguo is diploid, with oblong fruit, pointed beak and medium-sized fruit. Soft and ripe pulp is yellow to golden yellow, sweet, tender and full of flavor. The optimum storage temperature should be (1.5 0.5)℃ to reduce the damage and decay in cold storage. This variety is widely planted in Meixian County, Shaanxi Province, China. This variety is suitable for greenhouse cultivation, with the plant spacing of (3.0 ~ 3.5) m× (3.0 ~ 4.0) m, which will be severely shrunk, pruned and rejuvenated in winter. The stout spring shoots of that year were selected as the fruiting mother vines. Pruning should be strengthened in summer to ensure the illumination of orchard.
What are the nutritional differences and price differences among kiwifruit, kiwifruit, olive fruit and golden fruit?
Color is the difference. In addition, there are less yellow hair and more green hair.
In the same mature state, golden fruits are sweeter, more nutritious and more expensive.
The green fruit is sweet with a little sour taste, and the VC content is relatively high.
