According to the experimental practice in recent years, Xihonghang double-strain cultivation can increase production by 20% to 30% per mu compared with traditional single plant cultivation. In addition, the tomatoes cultivated in double plants have large fruits, fewer hollow chambers and better quality, and have improved commercial value. First, the reasons for the double-strain cultivation increase 1 compared with the traditional single plant cultivation, the two-plant tomato leaves more reasonable distribution, thus improving the utilization of light energy. 2 The relative increase in root system is conducive to the absorption of moisture and mineral elements. 3 Reduced the rate of seedling voids, making the population structure more reasonable. Second, the specific method of the two-plant cultivation Select two plants with uniform growth and seeding are planted in one hole. The distance between the two plants is 8 cm to 10 cm. The row spacing can be determined according to the variety, soil quality and moisture conditions. After easing the seedlings, growing for a period of time sometimes results in a large and small plant. In order to prevent the phenomenon of small seedlings being bullied, the following measures can be taken: 1 The big seedlings will fight early to reduce the nutrition area and inhibit their growth; the seedlings need to fight late to increase the nutrition area and promote the growth of branches and roots. 2 Hand-hold the base of the seedlings 5 ​​cm from the ground, twist half a turn, or make it appear to crack, so as to control the growth of large seedlings. 3 At the beginning of the kidnapping, the big seedlings can be tilted to a larger angle to control their growth; the seedlings should be smaller in inclination or in an upright position to promote seedling growth.
The appearance is tan, and the cork is red-brown at the flaking; there are intermittent stripes on the branches, nodules are enlarged, and the shape is like a bead. Most of the hard and delicate roots and fibrous roots are born, and some surfaces are smooth and smooth, such as stalks. It is commonly known as "crossing the river branches" or "crossing bridges"; there are brown scales on the upper part, and there are residual stems or petioles that have not been cleaned at the top. The quality is firm and hard, the section is irregular, the skin is dark brown, the wood is golden, the rays are cracked, the central pith is red and yellow, and occasionally hollow. Odorless, very bitter taste, chewing saliva can be dyed red and yellow. It is better to use fat, beaded, solid, red-yellow, no residual stems and fibrous roots.
