Due to the temperature and shade conditions and the high temperature, strong light, and low humidity conditions, the tomato in autumn in the greenhouse is under the conditions of temperature control, shade and flowering, respectively. Therefore, relatively fine production management measures are required accordingly. . Otherwise it is prone to malformation problems. Usually we see more cracking and stalemate. However, some seedlings that are over-shaded during the nursery period are prone to empty fruit at the beginning and end of the results. In general, the congenital cause of horizontal cracking and capping of tomato fruit is caused by insufficient supply of boron for calcium in flowering plants during flowering. Low-temperature drying is also not conducive to the absorption of calcium and boron, so cracking at low temperatures is also very serious. When the management conditions of the greenhouses are unbalanced, tomato plants will return to a state of vigorous nutrient growth for a short period of time. It will also cause fruit cracking. The unsteady fruit is due to the unfavorable temperature, light and other conditions of the tomato when flowering, or the flowers that would otherwise fall, treated with growth regulators, inhibited the formation of the layer, and barely sat fruit, because too few photosynthetic products were obtained. Can not expand, forming a small stiff fruit. Similarly, the empty fruit is due to the development of tomato flower buds, due to the lack of high temperature and sunshine, and secondly because of the large concentration of growth regulators used or the premature treatment of hormones. The empty fruit we see in the field is mainly caused by improper use of hormones.

Targeted management measures: (1) Based on experience, avoiding high temperatures, excessive shading, and excessive water supply during nursery to transplanting is a critical period for controlling flower bud differentiation conditions, and balanced temperature, humidity, and lighting conditions must be strictly met. It is the guarantee for the normal growth and development of the tomato in the late autumn. (2) The use of hormones in tomatoes in the greenhouses of the autumn gardens requires more care. If there is no certainty, it is best to spray a small amount to observe the effect, otherwise the negative consequences will be great. (3) In addition to the balanced control of environmental conditions during the fruiting period of tomato flowering, if signs of cracking are found, calcium supplementation and boron supplementation should be applied immediately. However, spraying fertilizers containing calcium and boron, usually in the form of spray fertilizer, can solve the problem. (4) Due to the restriction of the cultivation environment, the tomato in the greenhouse of the autumn eucalyptus requires timely fruit thinning above the second ear, and up to three fruits per panicle when growing densely, and up to four. In this way, the supply of nutrients can be balanced, and the phenomenon of fruit cracking and fruit cracking can be reduced.
