Embodiment Construction

[0016] The principles and features of the present invention are described below in conjunction with specific examples, which are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0017] A method for planting lettuce in a greenhouse, comprising the steps of:

[0018] (1) Field selection: continuous cropping of lettuce is avoided, and it is better to rotate with gramineous crops. Generally, paddy field soil is suitable. The field requires high terrain and convenient irrigation and drainage.

[0019] (2) Variety selection: Choose cold-resistant and frost-resistant early-maturing varieties. Such as Kexing No. 1, Zhongdu cold-resistant Erbaipi, cedar pine, hanging silk red and other lettuce varieties.

[0020] (3) Timely sowing: Generally, it is planted two days before and after September 10. The amount of seed used per mu needs to be sown about 50g, the seedling order is 30-50 days, and the planting period is before O...

Abstract

The invention relates to a plantation method for greenhouse asparagus lettuces. The method comprises the following steps of (1) selecting a field, preferentially a paddy rice field and requiring high terrain, (2) selecting varieties: preferentially cold-resistant early-maturing varieties, (3) broadcasting two days before or after September 10th, (4) fixed planting: deeply ploughing and turning over soil one week in advance and applying enough base fertilizer for one time, (5) watering human-animal manure water for root fixation after fixed plantation and applying human-animal manure water and urea to prompt seedling growth after five to seven days, (6) applying human-animal manure water and potassium chloride mixing liquid each seven days during small disc installation, and (7) digging caves and applying 50g of 7:3 NPK compound fertilizer and oil cake compound fertilizer between plants during stem expansion primary period. By the use of the plantation method, high asparagus lettuces output can be achieved, consumer eating demands can be met and economic development can be promoted.
