Embodiment 1

[0017] 1) Selection of seed potatoes: choose medium-sized sweet potatoes with long slopes, straight, uniform, no ribs, bright red skin, and no pest spots as seeds;

[0018] 2) Seed potato disinfection: Soak the potato seeds in a 600-fold mixture of 80% trichlorfon and 80% carbendazim for 1 hour for disinfection;

[0019] 3) Seedling land construction: choose a well-drained paddy field without sweet potatoes or water spinach as the seedling land, apply 5 kg of phoxim granules per mu to disinfect the seedling land, and apply 50 loads per mu, that is, 2500 kg of decomposed farmyard manure as base fertilizer;

[0020] When the seedling field is in a virus disease or scab or soft rot disease area, before disinfecting the seedling field, it is necessary to dig out all the original sweet potatoes and potato seedlings within 500 meters around the seedling field to cut off the spread of pathogens and poisonous insects the above diseases;

[0021] 4) Planting specifications: plant see...

Abstract

The invention discloses seedling growing technology of Guangpo red sweet potatoes. The technology includes the following steps: selecting excellent potato seeds, disinfecting the potato seeds, disinfecting seedling growing land, applying a base fertilizer on the land, planting disinfected potato seeds in the seedling growing land in spaced mode, spraying pesticide at regular intervals to prevent insects after seedlings of the potato seeds emerge, shearing the seedlings when the potato seedlings grow to 50-60cm and shearing the seedlings in circulation mode after the potato seedlings grow out again to obtain seedlings in a plurality of batches. By means of the seedling growing technology, proper seedling growing, sufficient seedling growing and strong seedling growing can be conducted, seedling growing cost is reduced, and seedling quality and transplantation survival rate are improved.

Description

technical field [0001] The invention relates to a seedling raising technology of sweet potato, in particular to a seedling raising technology of Guangpo red sweet potato. Background technique [0002] Guangpo red sweet potato is a traditional fine variety planted in coastal areas such as Fangchenggang City and Dongxing City in Guangxi. It is said that local farmers bred it from the mutant sweet potato varieties brought by Fujianese during the Kangxi period of the Qing Dynasty. The leaves of Guangpo red sweet potato are palm-shaped and five-pronged, the stem is dark green with a little purple red, the plant type is half-planted in the early stage, the stem is medium-long and the stem is medium-thick in the later stage of growth, the growth period is 130-140 days, and the potato flesh is pure white. The skin is light red, the shape of the potato is relatively round and short, the weight of the potato is medium and small, the content of starch is high, the taste is powdery, and...
