Continuous coring and pruning of small tomato
Tomato is a creeping crop, but it is often cultivated vertically by introducing frame in cultivation. Therefore, with the growth and extension of the plant, the farther away from the ground, the effect of flowering, fruit setting and fruit expansion is less ideal, and the yield can not be increased. In view of this bad situation, the continuous coring method can be used to increase the weight of the first ear and the number of flowers, so as to achieve the purpose of increasing production. The method is as follows: using the form of single stem pruning, retaining the first and second inflorescences, and then leaving 2 leaves above the second inflorescence to pick the heart. Let the lateral buds under the first inflorescence continue to grow as the main branch, and then leave 2 leaves above the fourth inflorescence to pick the heart, so that the lateral buds under the third inflorescence continue to grow as the main branch. The operation was repeated several times (the number of operations was determined according to soil fertility and plant growth). This operation method has lower plants, which is beneficial to the supply of fertilizer and water, and has earlier maturity and higher yield.
