Symptoms: abnormal enlargement of the middle or top of the zucchini fruit
Etiology: Although it has been pollinated, the fruit is incompletely fertilized, and seeds are only formed at the apex. Since auxin is produced during seed development, more nutrients are transported to this place, so the apex pulp tissue is preferentially developed, and it is particularly hypertrophic. Form big guagua. Insufficient nutrients, uneven water supply, and weakened plant growth can easily cause the formation of large-diarrhea melons. In the case of potassium deficiency, it is easier to form big guaguars.
Control methods: Ensure adequate supply of water and fertilizer, and to be uniform, in particular to ensure the supply of potash, so as to maintain the vigorous growth of plants. The operation of artificial pollination should be fine, thorough, and adequate, so that the pollen is evenly scattered on the stigma of the female flower.

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.
