How to achieve high yield of kiwifruit? What are the measures to prevent fruit drop?

With the development of planting technology, kiwi fruit is eaten all year round, among which red heart is more expensive and tastes better. Kiwi fruit can be processed into preserved fruit, fruit wine, etc. besides fresh food, which is deeply loved by consumers. Let's find out how kiwi fruit can be fruitful. What are the measures to prevent fruit drop?

How can kiwi fruit be fruitful?

1. Moderate close planting and garden construction

The traditional cultivation techniques of kiwifruit orchard generally adopt the plant spacing of 3 m ×4 m or 3 m ×3 m, which shows that the orchard can be completed in 3 years and can enter the peak fruit period in 6 years, resulting in a large amount of waste of space photosynthesis in the orchard and difficult to put into production early; while the dense planting technique adopts the plant spacing of (1~1.5)m×4 m, which shows that the orchard can be completed in 2 years and enter the peak fruit period in 4 years, with early production, high yield and good fruit quality.

2. Rationally cultivate trees

In the first year, the 2-year-old finished seedlings are planted according to the requirements of plant spacing, and then the stubble is carried out at the root neck, and a strong branch is selected to be introduced to the upper surface. In the second year, 1~2 main vines are left on each tree, which are respectively led to the space of the T-shaped frame, so that the fruiting branches are covered with the frame surface and begin to bear fruit. In the third year, 3~5 fruiting mother branches are selected, 7~8 buds are left on each fruiting mother branch, 3~4 fruits are left on each bud, and the yield per mu can reach about 1000 kg. In the fourth year, 7~8 fruiting mother branches are reserved for each plant, 7~8 buds are reserved on each fruiting mother branch, 3~4 fruits are reserved on each fruiting branch, that is, 25000 fruits are reserved per mu, and each fruit is calculated by 100 grams. The yield of the whole garden can reach 2500~3000 kg. This is repeated every year, and the peak fruit period can reach more than 20 years.

3. Strengthen soil, fertilizer and water management technology

High fertilizer and water must be ensured in order to obtain ideal effect in dense planting and high yield garden construction. In general, about 1000 kg of farm manure per mu is applied in autumn and winter every year, and in spring, topdressing is carried out according to the original fertilizer application amount of trees in full fruit period. In irrigation, it is necessary to ensure that germination water and fruit water are irrigated every 7 to 10 days to ensure the normal growth and development of kiwifruit. Green manure crops (clover, hairy vetch) are planted in orchards all the year round, and deep ploughing in autumn and winter is used as green manure for orchards.

2. What are the measures to prevent kiwi fruit from falling?

1. Scientific pollination

Firstly, pollinating trees should be allocated reasonably, and 81 is suitable, so it is necessary to change the wrong practice of reducing the proportion of pollinating trees by fruit farmers; Secondly, farmers should not store pollen for a long time (one year). The mixed pollen collected by fruit farmers is very low in purity and cannot be sealed. When stored for a long time, it cannot be kept dry. In addition, the temperature cannot be stabilized below minus 18℃, so it is recommended not to store it; Thirdly, the pollen collection process should not be exposed to the sun and should not exceed 28℃; Fourth, do not use a cooking machine or grinding groove to crush anther powder.

2. Strengthen water management at flowering stage

One is to maintain reasonable soil moisture content, soil moisture content is maintained at more than 65% of the maximum field water holding capacity; the other is to plant grass in the orchard, improve the field microclimate, increase the orchard humidity, and maintain the orchard air relative humidity above 55%.

3. Actively deal with bad weather

Pay attention to weather forecast. Spray amino acids, oligosaccharides or antifreeze before low temperature to improve tree resistance. When flowering encounters low temperature, if it is in early flowering stage, irrigate water and delay flowering to avoid low temperature at full flowering stage, so as to reduce loss. If the temperature is very low, before frost and ice come, artificial smoke can be adopted to prevent freezing. If it enters late flowering stage, it can be decided whether to take measures according to early pollination. Before the arrival of high temperature weather, irrigate water once before flowering. If there is no irrigation and high temperature is encountered during flowering, sprinkler irrigation or dropper facilities can be used to spray water. A small amount of water can also be irrigated at night or early morning to prevent flowers from falling due to excessive changes in soil temperature.
