The main reasons for strawberry boron deficiency caused by strawberry boron supplementation program are as follows: (1) soil acidification, boron is easily leached in large quantities; (2) application of excessive lime can easily cause boron deficiency; (3) soil drought, and plant growth is accelerated under high temperature conditions. Due to the poor mobility of boron in the plant body, it can not be timely and fully allocated to the urgently needed parts, and it may also cause partial lack of boron in the plant (4) less application of organic fertilizer, and it may also lead to lack of boron (5) over application of nitrogen and potassium fertilizers. Suppresses the absorption of boron.
Silage Wrap Film , also called silage Stretch Film,is the best and most advanced silage packing product on the farm in the world, which is produced by LLDPE and other metallocene material with blown technology for 5-layer film product. Silage Wrap packing film is applied in maize,whole-plant corn, alfalfa silage package field mainly.
We classify silage wrap films by its different width 750mm,500mm and 250mm for applications of different silage packaging machines in different countries and areas, or different colour,black , green and white in different sunshine area.
Silage Stretch Film`s Characteristics:
1: Functional film, special for protective performance
2: Good mechanism and stretch performance
3: Thickness even

How can we solve it?
The application of boron fertilizer in the base fertilizer appropriate boron fertilizer. When symptoms of boron deficiency appear, foliar spray of 0.1 to 0.2% borax solution should be promptly applied. 7 to 10 days, even spray 2 or 3 times. Since strawberries are sensitive to excess boron, the spraying concentration should be appropriately reduced during flowering, and can also be applied per acre or topped with 0.5 to 0.8 kg of borax.
Add organic fertilizer. The nutrients in organic fertilizers are relatively complete. In particular, it is necessary to apply more fertilizers such as golden bacon's starter, which contains more boron, can make the soil more fertile, enhance the soil's ability to retain water, relieve drought hazards, and promote root expansion. Increase the absorption of boron by plants.
Microbial fertilizer is applied. For example, the golden seaweed algae microbial fertilizer can make the strawberry root system a particularly favorable micro-ecological environment, can promote the development of strawberry roots, enhance the ability of salt and alkali resistance and drought resistance, and promote strawberry nutrition of phosphorus, potassium, iron, manganese and other nutrients. Absorption and utilization; regulation of soil pH, so that the acidic or alkaline soil tends to be neutral; can enhance the strawberry's defense resistance against disease, and the golden babe seaweed microbial fertilizer is a good effect of your lack of nutrients.
Reasonably irrigated. Ensure the water supply of plants, timely watering, increase soil soluble boron content, in order to facilitate plant absorption, prevent soil drought or excessive humidity, affect the absorption of boron in the root system. Details can visit the website or consult.
