Summer and autumn sowing seeds from April to June, planting from May to July, and harvesting from July to September. Its main growth period is at a high temperature, light and rainy season, affecting the tomato growth, the disease is heavy, the yield is low, and the requirements for varieties are higher. Should choose strong growth, disease resistance, high temperature resistance. Crack resistant varieties or special tomato varieties.
The best forehead of the tomato is the onion garlic vegetables, followed by the leguminous and melon vegetables. It is best not to choose peanuts as a forehead. Former crops should be unloaded and cleaned up. It is then sterilized and ploughed and tomato cultivation is performed.
Premature spring tomatoes can be planted with autumn cabbage, radish, etc., after the type of early-season cultivar is grown. Infinity-type tomatoes are simmered with spinach or other leafy vegetables that are sowed in winter. Protected areas can be grown in early spring and can be planted in later pods.
