Embodiment 1

[0011] We conducted fertilization research at the Changzhou red taro planting base, and selected the newly planted and one-year-old red taro test sites. The specific steps are to plow the ground and apply basal fertilizer ten days before the red taro seedling transplantation. When fertilizing, commercial organic fertilizer (full N, P, K nutrient content is greater than 3%wt, organic matter content is greater than 30%wt), multi-element nutritional active materials ("Saizhong 28") and compound fertilizer (N-P 2 o 5 -K 2 O= 15%-15%-15%) according to the ratio of 85% : 5% : 10% to make base fertilizer, the dosage is 600 kg per mu. After ridging, spray 40 kilograms of amino acid foliar fertilizers on the soil surface per mu. Spray a high-nitrogen foliar fertilizer (N%=25%, P 2 o 5 %=10%, K 2 O=20%), use 60 kg per mu each time. Spray high-nitrogen foliar fertilizer once again when the taro starts tillering, with an amount of 60 kg per mu. When the new corm begins to expand, ...

[0016] Fertilization research was carried out in the Changzhou red taro planting base, and the newly planted and one-year-old red taro test sites were respectively selected. The specific steps are to plow the ground and apply basal fertilizer ten days before the red taro seedling transplantation. When fertilizing, commercial organic fertilizer (full N, P, K nutrient content is greater than 3%wt, organic matter content is greater than 30%wt), multi-element nutritional active materials ("Shenzhen VI 54") and compound fertilizer (N-P 2 o 5 -K 2 O= 15%-15%-15%) mixed according to the ratio of 95% : 1% : 4% to make base fertilizer, the dosage is 600 kg per mu. Spray the soil surface with fulvic acid foliar fertilizer after ridging. The dosage per mu is 40 kg. Spray a high-nitrogen foliar fertilizer (N%=25%, P 2 o 5 %=10%, K 2 O=20%), 40 kg per mu. Spray high-nitrogen foliar fertilizer once again when the taro starts tillering, with an amount of 50 kg per mu. When the new c...

Embodiment 3

[0021] We conducted fertilization research at the Changzhou red taro planting base, and selected the newly planted and one-year-old red taro test sites. The specific steps are to plow the ground and apply basal fertilizer ten days before the red taro seedlings are transplanted. When fertilizing, commercial organic fertilizer (full N, P, K nutrient content is greater than 3%wt, organic matter content is greater than 30%wt), all-element nutritional active materials ("Saizhong 28") and compound fertilizer (N-P 2 o 5 -K 2 O= 15%-15%-15%) according to the ratio of 90% : 2% : 8% to make base fertilizer, the dosage is 600 kg per mu. Spray the soil surface once with seaweed foliar fertilizer after ridge formation. The dosage per mu is 50 kg. Spray a high-nitrogen foliar fertilizer (N%=25%, P 2 o 5 %=10%, K 2 O=20%), use 50 kg per mu each time. Spray high-nitrogen foliar fertilizer once again when the taro starts tillering, with an amount of 55 kg per mu. When the new corm beg...

Abstract

The invention provides a disease prevention and production increase fertilizing method for purple yams. Base fertilizer and additional fertilizer are applied in matching mode. The disease prevention and production increase fertilizing method for purple yams specifically includes the steps that the soil is turned up and the base fertilizer is applied 10 days before the purple yams are planted; all-element plant nutrition leaf fertilizer is sprayed on the surface of the soil once after ridging; high-nitrogen leaf fertilizer is sprayed when the red yams have three leaves; high-nitrogen leaf fertilizer is sprayed once again when seed yams begin to tiller; combined with ridging, 15-20kg of compound fertilizer and 15kg of potassium sulfate are applied per mu when novel corms begin to expand; high-potassium leaf fertilizer is sprayed once when the purple yams grow continuously; and multi-element plant nutrition leaf fertilizer is sprayed once again after ten days. A material adopted by the disease prevention and production increase fertilizing method for purple yams comprises N, K nutrients and secondary and trace elements required by plant growth. After the disease prevention and production increase fertilizing method for purple yams is used, production of the purple yams can increase by above 30%, commodification of the yams are improved greatly, and number of diseased yams is reduced remarkably.

Description

technical field [0001] The invention belongs to the technical field of high-efficiency agriculture, and in particular relates to a fertilization method capable of simultaneously increasing the yield of red taro and preventing and treating diseases of red taro, and a fertilization technique for overcoming obstacles to continuous cropping of red taro. Background technique [0002] Red fragrant taro is an excellent taro in Jintan City ( Colocasia esculenta Schott.) A local variety, belonging to the type of taro with many seeds. It has a long history of planting in the local area. According to historical records, it was designated as a tribute as early as the Ming Dynasty. This variety has a round body, a moderate size (about 50 g each), red skin and white flesh, and it is fragrant and delicious to eat. In addition to selling fresh products locally and in surrounding areas, processed products such as quick-frozen taro seeds are also exported to Japan, South Korea and other pl...
