High-yield fertilization methods for strawberries and solutions for soft fruit

Normally, February and March are the peak times for visitor traffic at strawberry picking farms, but due to recent weather conditions, the growth and yield of strawberries have not been good enough. Under these circumstances, fertilization becomes particularly important. So how can fertilization make strawberries high-yielding? What should be done about soft fruit? Below, these questions will be answered one by one.

I. Relevant information about strawberries

1. Origin of strawberries

The strawberry (pineapple strawberry) is a perennial herbaceous plant native to South America and is widely cultivated in various countries and regions. The main strawberry production bases in our country include Dandong City, Liaoning Province; Changfeng County, Anhui Province; Jurong City, Jiangsu Province; Shangtian Town, Fenghua City, Zhejiang Province; Luoxi, Changzhou City, Jiangsu Province; Yongren County, Yunnan Province; Zhongmu County, Zhengzhou City, Henan Province, and so on. Of course, now almost every province, city and region has strawberry picking farms, and friends who want to experience picking for themselves can also invite friends and bring family along. However, the price at picking farms is generally much more expensive than at supermarkets and fruit shops.

2. Strawberry picking time

The strawberry picking season is generally in February-March, but due to different regions, the picking time will also differ slightly. For example, the picking time in Guangzhou is December-February of the following year, and the strawberry picking time in Changping, Beijing is January-April. Strawberry picking may also be earlier or later due to changes in weather and other factors, so everyone can pay more attention to local strawberry picking information.

3. Price of strawberries

At present, in the Shandong area, the price of cream and Hongyan strawberry seedlings with a ground diameter of 0.2 cm and a height of 0.3 m is: 0.9 yuan/seedling for purchases of 100-999 seedlings, 0.6 yuan/seedling for purchases of 1000-9999 seedlings, and 0.25 yuan for purchases of more than 10,000 seedlings. In addition, the table below is a reference table of recent fresh strawberry prices in some regions:

II. How should strawberries be fertilized to achieve high yield?

1. It is not very difficult to fertilize strawberries for high yield. Generally, before planting, apply sufficient organic fertilizer as a base fertilizer. If barnyard manure is used, it must be well rotted.

2. During the fruiting period of strawberries, reasonable topdressing should be carried out. Generally, apply 4000 kg of high-quality farmyard manure per mu as a base fertilizer, combined with 50 kg of compound fertilizer. In the middle and late stages, combined with pesticide spraying, it can promote the development of fruit in the middle and late stages and increase fruit weight and sugar content; in addition, strawberry seedling fertilizer mainly consists of cake fertilizer, organic fertilizer, livestock manure, and so on.

3. When fertilization is insufficient, foliar fertilizer can also be sprayed appropriately, more organic fertilizer should be added, the content of soil organic matter should be increased, the amount of nitrogen fertilizer should be controlled, irrigation should be frequent, and soil moisture should be kept uniform.

III. What should be done if strawberry fruit becomes soft?

If strawberries have high yield but the fruit becomes soft, it not only affects sales but also makes them prone to rotting during transportation. So if you want strawberry fruit to be large and firm and sell for a good price, operate according to the following methods:

1. Strawberries should be fertilized reasonably

During the young fruit stage, supplement a small amount of nitrogen, phosphorus and potassium, and supplement more calcium, magnesium and medium and trace elements. Young fruit need a relatively large amount of calcium and magnesium. During the fruit expansion stage, balanced fertilization is required. Since strawberries are a continuous flowering crop, some strawberries need to expand, some are still young fruit, some are still flowering, and some are in the flower bud differentiation stage, so all of them must be taken care of.

2. Strawberries should use hormones reasonably

This is especially true when using swelling agents. They must be used according to the instructions, and the amount must not be increased at will. Otherwise, the fruit is prone to becoming soft, not resistant to transportation, and the plants will decline prematurely. Generally speaking, it is not recommended to use swelling agents on strawberries; other methods can be used to achieve the effect of fruit expansion.

3. Humidity should be well controlled at strawberry bases

High humidity inside strawberry sheds and ordinary watering can easily produce standing water on the surface of the plastic film. If young strawberry fruit remains in standing water for a long time, it will cause strawberry fruit rot, so under the condition of ensuring reasonable humidity, excess standing water must be drained. Strawberry fruit has no peel outside to block bites from aphids, mites and other insects; and once diseases such as gray mold, leather rot and fruit rot occur, young fruit is most likely to be harmed, and when it then comes into contact with water, it will lead to soft fruit and rotten fruit.
