[Reporter Yang Yuanting/Taipei Report] Water pears are one of the most important fruit crops in Taiwan, and Taiwanese pears are mainly planted in the grafted pear Hotaka grafted pear planting mode, and the operation period of grafted pear spikes is from December to the next year In February, it is easily affected by the cold snap. The application of Trichoderma microbial preparations at the Taichung Agricultural Reform Field of the Council of Agriculture can reduce the loss of pear ears by 20% due to cold damage, increase the weight of the fruit by 14%, and make the pears taste sweeter.

Taiwan’s pear planting area is about 5,200 hectares. The central part is the main cultivation area of ​​Taiwan’s pears, accounting for about 70% of the country’s total area. Taiwan’s pears are mostly planted by grafting pear ears. The temperature in low-altitude production areas often drops below 10 degrees, causing the root system of the rootstock and the sap in the trunk to stop flowing, and the nutrient supply in the underground is insufficient, which makes the pear ears unable to grow smoothly and suffers. Lan Xuanjin, an assistant researcher at the field, applied research and development The Trichoderma TCT768 and TCT-P001 microbial preparations can increase the toughness of pear ears in low-temperature climates, and can obtain sufficient nutrients for the growth of pear ears in an environment with a continuous low temperature of below 10 degrees for more than 22 hours.

According to Lan Xuanjin, the field test proved that the damage rate of spikes was reduced by 15-23% compared with untreated ones; in the subsequent fruit growth, it also had the effect of promoting fruit growth and expansion, increasing the average fruit weight by 14%, and Improve fruit flavor and sugar content above 1°Brix, in addition, the amount of Trichoderma biological agent used is not large, and will not increase the cost of farmers' planting.

Zhonggaichang further pointed out that the application of microbial preparations can significantly reduce the damage caused by the cold current of Gaojie pears, and can promote fruit growth and improve quality.

Microbial preparation application technology has completed the evaluation of the validity of strains and established a field operation model. Farmers and operators can contact the field.

The raw material of the microbial preparation is Trichoderma.
