Embodiment 1

[0016] The present invention provides a kind of eggplant sparsely planted high-yielding open field planting method, specifically comprises the following steps:

[0017] Step 1, variety selection: select hybrid first generation, long growth period, early, mid-maturity and high-yielding eggplant varieties as scion varieties, and select special rootstocks for eggplant;

[0018] Step 2. Grafting: start grafting when the rootstock has 5-6 leaves and the eggplant seedling has 3-8 leaves, keep 2 true leaves on the rootstock, cut the stem of the rootstock crosswise with a blade, remove the upper part, split in the middle of the stem, and cut downwards About 1.0-1.5 cm deep, pull out the scion seedlings, keep 2-3 true leaves of the seedlings, remove the lower end with a knife, cut the remaining upper stem incision into a wedge shape, insert the scion into the incision of the rootstock, and after alignment, use The clip is fixed, and the height of the grafted part of the seedling stem f...

Abstract

The invention provides an open-field planting method for high-yield and thin planting of eggplants. The method comprises the following steps: (1) variety selection: selecting an eggplant species whichis of a first hybrid generation and has early middle maturity and high yield; (2) grafting; (3) thin planting: constructing deep ditches and high ridges, performing open field thin planting and cultivation, planting 300-500 plants per mu, and adopting a plant spacing of 120-200 cm; (3) field management: applying sufficient base fertilizer, and performing topdressing once before harvest is conducted; (4) management with no pruning: performing natural growth, and conducting pest and disease control; and (5) timely harvest. According to the open-field planting method for high-yield and thin planting of eggplants, the eggplants are cultivated by using the thin planting open-field planting method, so that improvement of the yield and quality of the eggplants is achieved at the same time; the number of eggplants per plant reaches 40 or above, the weight of one single fruit reaches 58 g, the content of VC reaches 54.12 mg / kg, and the economic output reaches 59824.16 kg / hectare; and when theeggplants is compared with eggplants cultivated by using a traditional eggplant cultivation method, the yield is increased by 49.1% or above.

Description

technical field [0001] The invention relates to the technical field of vegetable planting, in particular to an open-field planting method with sparse planting and high yield. Background technique [0002] Eggplant, native to Indonesia, was introduced into my country in the Ming Dynasty. The whole fruit can be used as medicine, which integrates edible, medicinal and ornamental. Especially in European and American countries, it is an important ornamental plant. The nutritional value of eggplant is very high, and it is relatively comprehensive, especially rich in vitamins A, B, and C, ranking first in melons and eggplants. According to measurements, every 100 grams of eggplant contains 22 mg of vitamin A, 10.7 mg of vitamin B, and 84 mg of vitamin C, which is 6 times that of cucumber, 7 times that of tomato, and 10-20 times that of loofah, squash, and muskmelon. Eggplant is also high in protein, fat, and carbohydrates, and contains essential calcium, iron, phosphorus and oth...
