Yazu No. 3 (Tomato)
Source: from the Asian vegetable Research and Development Center.
Main characters: precocious, self-topping type, strong growth potential, many fruits, cherry type, smooth and round, bright red color, single fruit weight of about 13.5g, soluble solids content as high as 5.5%, good quality, good taste, high early yield, good yield, 667m2, yield of more than 4000 kg, strong disease resistance, resistance to storage and transportation, high economic benefits.
Cultivation points: suitable for early-maturing cultivation. Seedlings raised in cold bed in greenhouse should be sown in early November, while seedlings raised in electric hotbed should be sowed in early January. Strengthen management at seedling stage, cultivate strong seedlings, use nutrition bowl to divide seedlings with 2 leaves and 1 heart, the distance between seedlings is 10-10 cm, when there are 8-9 true leaves, they should be planted in time, those cultivated in greenhouse do not need to refine seedlings, and those who are cultivated with plastic film mulching in open field should refine seedlings at low temperature one week before planting. Apply sufficient base fertilizer, 3000 kg of rotten barnyard manure and 40 kg of compound fertilizer per mu. The general width of the border is 1.4 meters (even ditches), with 2 rows of species in each border and 0.4 meters between plants. Double-pole pruning was used, and 10-15ppm anti-falling element was sprayed every 2-3 days in the early stage to promote flower protection and fruit setting. To strengthen fertilizer and water management, instead of topdressing nitrogen fertilizer after the result, 0.2-0.5% potassium dihydrogen phosphate can be used for foliar topdressing to improve quality. Pay attention to the prevention and control of diseases such as Botrytis cinerea and harvest in time when the fruit is red-ripe.

Lengthening tomato fruit method
After the first generation tomato is harvested, the following three methods can be taken to make the tomato blossom and bear fruit again and improve the economic benefit. Seedling pressing method: after the first generation tomato is ripe and harvested, cut off the withered branches and yellow leaves, retain the new branches with exuberant regeneration ability, and dig a fertilizer ditch 20 cm long and 15 cm deep on one side of the trunk and apply fertilizer. After fertilization, the trunk is buried in the ditch and watered to make the vine take root quickly. In this way, the new root and the old root absorb water and fertilizer together, the plant type grows rapidly, and the tomato can blossom and bear fruit again. Plant cutting method: cut off the first generation tomatoes after harvest

Taiwan small tomato varieties, such as "Yasu II" and "Hongbao No.1", have the characteristics of cold tolerance and high temperature resistance, and can grow normally at temperatures between 0 ℃ and 35 ℃. This variety has a long growth cycle and can generally continue the fruit for 1 and a half to 2 years. A bunch of fruit can bear about 30 grains. The fruit is heart-shaped, red in color, smooth and attractive. The experimental planting shows that the fruit per plant is more than 10 kg, the yield per mu can reach 20,000 kg, and the income per mu can reach 80,000 yuan.
