Advantages of grafting and cultivation of watermelon: It is beneficial to control root nematodes; It is beneficial to continuous cropping of watermelon; It is conducive to early maturing; It is conducive to moisture-resistant cultivation; It is beneficial to increase yield. First, choose the rootstock. Grafting should be selected for strong disease resistance, high affinity, and good rootstock after grafting. The round gourd is the most suitable. The round gourd shows high survival rate, which is not only wet and cold, but also strong and resistant. Second, reasonable arrangement of rootstock, scion varieties sowing period. In order to adapt the growth of rootstocks and panicles for grafting, it is generally necessary to sow the rootstock first, and the latter species of watermelon scion. The rootstock seeds are usually seeded in small film bags filled with nutrient soil, but the nutrient soil should not be too fat, as long as the grains are fine and loose. Then put a small film bag into the seedbed and cover it with moisture on the bed. After one week, the seeds of the scions are sown in another nursery box or on a nursery bed. It is also necessary to protect the scion seeds from rain and rotten species. Third, when grafting, the thickness of the anvil and ear seedlings must be equal. If the rootstock is small, the embryonic axis is fine, when grafting, inconvenient operation, the rootstock easily crack; if the rootstock is large, the medullary cavity of the embryonic axis is also large, it is difficult to heal after grafting, and the appropriate grafting period should be controlled by the flattening of the rootstock cotyledon, and the true leaf just When it appears, the scion species seedlings emerge from the top shell and the cotyledons begin to turn green from yellow to blue. If rootstocks and other scions are present, the true leaves of the rootstocks can be removed first to thicken the cotyledons, thicken the embryonic axes, or slightly pour the rootstock, suppressing the growth, and pulling it out in advance. A container allows its buffer to grow. When it is grafted on a large area, in order to avoid the time and concentration of grafting, it must be sown in batches in stages so that the grafting date can be appropriately set. Must be sprayed to prevent disease before grafting. Fourth, grafting together and methods. 1. Insertion: Grafting wooden knife made of wolfberry is inserted into the hypocotyl axis from the top of the cotyledonary node of the flat pu anvil, temporarily not pulled out, after the scion is cut, the wooden knife on the anvil is pulled out, and the scion is inserted immediately. The stable insertion of the hole opened by the wooden knife is completed. 2. Connect: (1) First dig the anvil and try to retain the root group. Use about 1 cm from the bottom of the cotyledon to make a bevel cut from the top to the bottom. The incision is about 0.5 to 0.7 cm deep. For 3/5 of the shaft, the incision should not be too short, nor should it be too shallow or too deep. (2) The scion was also raised by the nursery box, and the root group was kept as far as possible. The cotyledon was cut down from the bottom of the hypocotyls at 1 cm from the cotyledon. The incision was about 0.7 cm long, and the section was straight and deep. For 3/5 of the shaft, the incision should not be too short nor too shallow or too deep. (3) Make the incisions of the scions and root anvils fit in each other and close them well. At this time, the cotyledons of the scions are in a parallel state, and they are gently clamped with the grafting clips, with the spikes in the clips, and the root anvil is in the clip outer file. Fifth, the management of grafted seedlings. There are many factors that directly affect the rate of grafted seedlings into sea cucumbers, especially since the first few days of management are the key to success. After grafting, the grafted seedlings should be transplanted into the nutrient bowl in time and be irrigated with water, but do not splash on the wound. In addition, no water can directly contact the grafted seedlings until survival. Even if pests and diseases occur, they must wait 7 or 8 days to survive and then spray medicine, and then cover with a film, so that warming and heat preservation countries, grafted seedlings in the first 3 days for shading, still need to add a layer of opaque outside the film The cover, after 3 days, will be removed sooner or later. After one week, all of them are not covered, so that the hypocotyls are easy to elongate, yellow, and the seedlings are not robust. During the cover period, the temperature within the membrane is required to be 25°C-30°C during the day and 20°C during the night. The temperature during the day cannot be too high. , Too high will burn the seedlings, to prevent dead seedlings, the first three days is strictly prohibited filming ventilation and watering. If there are lateral buds on the rootstock, they should be removed in time with tweezers. Six grafted seedlings transplanted. Grafting seedlings can not be planted densely, but to sparse plant spacing 1.8 meters spacing, spacing 2 meters.
The goji berry is very healthy and therefore high on the list of super foods. The berry (Lycium barbarum) belongs to the Nightshade family and originates from Asia. In China, goji berries have been used for some four thousand years in medicine and food.
Goji berries are very vesatile: they can be used in infusions, medicines and dietary suplements, and it is eaten fresh. Dried Goji Berries can be eaten as they are, but are also delicious when added to bars, baked goods and muesli.
