Winter fertilization fruit trees winter fertilizer to cattle tread fertilizer, pig manure, oil dry, plant ash and other organic fertilizers. Fertilization method: The main method is ring-shaped open-pit fertilization and strip-shaped furrow-based fertilization. Ditch the canopy under the drip line, and the depth is suitable for seeing tree root (generally 25-35 cm). Number of fertilization: Saplings apply 1-2 kilograms of organic fertilizer per plant, plus additional 0.3-0.5 kg of chemical fertilizer (carbon ammonia); the resulting tree is applied with 3-5 kg ​​of organic fertilizer per plant, plus 0.5-1 kg of phosphorus and potassium fertilizer.
In addition, for the fruit trees rich in saplings such as saplings, persimmons, and walnuts, it is necessary to pay attention to the management of frost-proofing through measures such as tree-soil cultivation, tree-white coating, and trunk-sowing.
hydroponics system-nutrient technique (NFT)
NFT does not give average support to roots. Typically, the roots sit in a long sloping channel irrigation (Fig. 1.1). The nutrient is introduced into the high class of the canal and allowed to flow over the roots after which it drains into the nutrient tank. This is then re-pumped back into the channel to repeat the watering process.
This feed cycle can be intermittent or continuous. An & lsquo; The intermittent 'rss cycle is controlled by the clock and repeated several times per hour. this is sometimes called the "NFT pulse". The NFT pulse usually achieves better aeration of the roots as the roots are exposed to air between each feed. A & lsquo; continuous' rss cycle works non-stop. This is often used in commercial operations.
You can easily grow your favorite flowers at home without muddy mess and need to water your plants regularly.
Hydroponics is an ideal way to grow plants in urban areas. This makes it a great hobby that helps you to relax and it is fun to watch the hydroponic plants grow in the garden nft.
