Problems solved by technology

The general way to prevent asparagus diseases is to apply a large amount of pesticides, which will increase the pesticide residues in tender stems and seriously affect the quality of asparagus
In the two seasons of summer and autumn, the greenhouse is fully covered and planted, the temperature difference between day and night becomes smaller, the accumulation of nutrients decreases, and the quality of asparagus deterio

Embodiment 1

[0029] Embodiment 1 takes spring sowing seedling raising as an example

[0030] 1. Cultivate high-quality seedlings

[0031]On April 7, 2013, the seeds were sun-dried for 2 days. On April 9, 2013, the seeds were soaked in warm water at 30°C for 3 days. The water was changed every day, and the seeds were often washed by hand. After the seeds have absorbed enough water, they are taken out and put into gauze, and placed in a seed incubator at 28°C for constant temperature cultivation for 4 days. At this time, more than 20% of the seeds are white.

[0032] Mix vegetable garden soil: organic fertilizer: ridge chaff ash = 5:1:3 to form a seedling substrate, and then add organic-inorganic compound fertilizer (N:P 2 o 5 :K 2 O=12:5:13) 0.1kg and carbendazim (50% wettable powder) 0.5g, sieved and put in a nutrition bowl for later use.

[0033] Water the nutrient pot before sowing, then sow asparagus seeds in the nutrient pot, one seed per pot, and then cover with about 2 cm of nutr...

Embodiment 2

[0054] Embodiment 2 raises seedlings with winter sowing

[0055] 1. Cultivate high-quality seedlings

[0056] On November 5, 2012, the seeds were sun-dried for 2 days. On November 7, 2012, the seeds were soaked in warm water at 30°C for 3 days. The water was changed every day, and the seeds were often washed by hand. After the seeds have absorbed enough water, they are taken out and put into gauze, and placed in a seed incubator at 28°C for constant temperature cultivation for 4 days. At this time, more than 20% of the seeds are white.

[0057] Mix vegetable garden soil: organic fertilizer: ridge chaff ash = 5:1:3 to form a seedling substrate, and then add 0.1kg of organic-inorganic compound fertilizer (N:P:K=5:5:5) and 50% carbendazim 0.5g, sifted and put in a nutrition bowl for later use.

[0058] Before sowing, the nutrient bowl was watered thoroughly, and on November 14, 2012, the asparagus seeds were sown in the nutrient bowl, one seed per bowl, and then covered with ab...

Embodiment 3

[0078] Embodiment 3 (the present invention method and planting in the open field, greenhouse full coverage planting comparative test)

[0079] Test location: The test is located in the asparagus base of Hangzhou Jiahui Agricultural Development Co., Ltd.

[0080] Test time: 2013-2014

[0081] experimental design:

[0082] 1) The method of the present invention establishes 3 repetitions with open field planting and greenhouse full coverage planting, each repeating 100m 2 .

[0083] 2) the inventive method adopts the method with embodiment 1

[0084] 3) Open-air planting: Seedling raising, transplanting, time and method for keeping stems for the second time, fertilization in clearing the garden, prevention and control of diseases and insect pests, harvesting are the same as in Example 1, and the greenhouses grow under open-air conditions throughout the year without covering the film.

[0085] 4) The whole covering planting in the greenhouse: seedling raising is the same as th...

Abstract

The invention discloses a technology for harvesting and cultivating asparagus at all seasons through twice stem keeping, twice film coverage and twice film uncovering for asparagus. The four-season asparagus harvesting and cultivating technology comprises the following steps: covering a film for the first time in the middle ten days of November, keeping spring mother stems in the middle ten days of April and uncovering the film for the first time in the middle ten days of May; covering the film for a second time in the middle ten days of August and keeping autumn mother stems, and uncovering the film for a second time in the first ten-day period of September; harvesting winter asparagus from the last ten-day period of December to the last ten-day period of January, harvesting the spring asparagus from the first ten-day period of February to the first ten-day period of the April, harvesting summer asparagus from the middle ten days of May to the first ten-day period of August, and harvesting the autumn asparagus from the first ten-day period of September to the first ten-day period of November. According to the technology harvesting and cultivating asparagus at all seasons through twice stem keeping, twice film covering and twice film uncovering for asparagus disclosed by the invention, the mother stems are kept by sheltering from rain, so that the occurrence of stem wilt can be reduced, the quality of asparagus immature stems can be improved, the asparagus is harvested in advance, the harvesting period is prolonged, the annual supply of the asparagus is almost realized, and the purpose of increasing the yield is realized.

Description

(1) Technical field [0001] The present invention relates to a method for cultivating asparagus, in particular to a method for cultivating bamboo shoots in four seasons by keeping the stems for the second time, covering the film for the second time, uncovering the film for the second time, and harvesting bamboo shoots in four seasons. ) and an improved cultivation method based on the open field cultivation method. (2) Background technology [0002] Asparagus (Asparagus officinalis L.), scientific name Shi Diaobo, is a perennial herbaceous plant of the genus Asparagus in the family Liliaceae. It enjoys the reputation of "King of Vegetables" and has huge market potential at home and abroad. [0003] Asparagus is generally planted by conventional open-field cultivation or full coverage in greenhouses. The climatic conditions in the southern region are warm and humid, high temperature and rainy in summer, and the rainy season every year, all of which provide strong conditions f...
