After the emergence of the pumpkin, use a deep loose ruler to loosen 25-30 cm deep in the ditch, which can play a role in preventing cold, increasing temperature, loosening soil, weeding, water storage, preserving earthworms, preventing disease, reducing wind erosion, and water erosion. When it grows to 3-4 leaves, it will be cultivated by cultivators.
Centering (pickling). The squash grows to four compound leaves, and artificially set the core (also called topping) in the morning 5-10, in the afternoon 3-7, artificially remove the growing point of the pumpkin. To remove completely and not hurt the fourth leaf. Try to avoid the high temperature period at noon so that the excessive water loss of the pumpkin will affect the growth. The core setting time will be on June 10-25. After vines and vines are set, the white squash seeds grow from the first, second, third and fourth sections of the leafhopper, destroying the vines on the first and second sections. The earlier the better, avoid the first and second seedlings. Excessive influence of three or four vines. Leave behind the vines in the third and fourth quarters to continue growing. When the length of the three or four vines reaches 35-50 cm in length, artificial vines (cis vines) are introduced to guide the two vines to both sides of the main planting ridge, leading along the direction of 20-30 degrees of ridges. The direction of the vines should be the same among the plants so that they will not interfere with each other.
Artificial pollination. After the vine grows, the first vine spreads to the seventh quarter. When the four vines reach the ninth, they usually produce the first female flower. After the female petal is unfolded, the pistil stigma can receive pollen (stamen pollen) to fertilize. At this time from 5 to 9 am every day, the newly opened male flower core (the stamen's pollen stick) is gently removed from the field and gently rubbed against the pistil to adhere the pollen to the pistil stigma. Each stamen can only adhere to 2-3 pistils. Be sure to choose between 5-9 am every day.
Pressure vines. After artificial pollination by female flowers, the petals began to wil to close and it was confirmed that they had been pregnant. A small pile of soil was pressed on the front section of each melon and the vines were brought into close contact with the ground, and secondary roots were grown to supply the seeds with water and nutrients. When watching the vines, it is best to leave the cucurbits on top of ridges or to pile up a small mound, leaving the melons on top to avoid overdriving the disease caused by the late rain.
Remove two vine growth points. After each vine spreads melons, leave four leaves behind the melon, and then remove the top growing point of the melon and ensure that there is sufficient moisture and nutrient supply without loss.
Killed Sun Man. After the two vines have been picked up, they will grow many vine vines. At this time, they will have to look at the fields for a long time and find that all the vines are born and immediately destroyed.
Weed net weed. At present, there are not many chemical herbicides for pumpkins, and there are fewer agents for broadleaf weeds, and they will form the key when they are used more or less. It is proposed that weeding herbicides should be used instead of broadleaf herbicides.

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.
