This kind of gourd has good quality and high yield

Gourd has high edible value and economic value, attracting a large number of farmers to plant it. Although gourd is delicious and has a high yield, it is not good to grow. The main reason is that if the gourd is not well grown, it will easily appear bitter, which will affect the taste and quality.

Why does gourd have a bitter taste?

The bitter taste of gourd gourd is caused by the accumulation of a class of substances called cucurbitacin. The main causes of occurrence are as follows:

1. Varieties vary greatly in the content of cucurbitacin. If there is bitter melon pollen in the reserved varieties during the seed retention process, the impure seeds will also have a bitter taste.

2. Cultivation reasons (1) For planting gourd in spring, if the planting is too early, the temperature difference between inside and outside the shed will be large, and bitter melon is likely to appear.

(2) During the fruiting period, if the nutrient supply is insufficient, the gourd is prone to bitterness and deformity.

(3) Partial application of nitrogen fertilizer in the early stage may cause bitter melons.

(4) If the soil is too dry, bitter melon will appear.

(5) The bitter taste of gourd can easily be caused by injury of the vines during cultivation.

Measures to prevent bitterness of gourd

(1) Select varieties correctly. It is recommended to choose varieties without bitter taste, and to introduce varieties from other places for planting, which need to be suitable for the current growth environment. It is recommended to try planting in a small area first, and planting different varieties separately to avoid stringing powder.

(2) Sowing in an appropriate time. When planting gourds in a greenhouse, heat preservation should be done after sowing to ensure that the night temperature is not lower than 15°C to avoid excessive temperature differences. Especially in the fruiting period, pay attention to ventilation in the greenhouse at noon on a sunny day to reduce the temperature difference between day and night.

(3) Reasonable fertilization. The gourd grows fast and has a strong fruiting ability. The maximum yield per mu can reach tens of thousands of catties. Therefore, the amount of fertilizer is also large, and sufficient base fertilizer must be applied before planting. The gourd should be harvested in time when it is mature, especially the root gourd should be harvested in time and topdressed in time. Generally, topdressing should be done every time it is harvested. The topdressing is mainly compound fertilizer, with 15-20 kg per mu.

(4) Keep the soil moist. The root system of gourd gourd is well developed and requires a large amount of water. It should not be too dry. During the whole growth period, the soil must be kept dry and wet. (5) Strengthen management. Pruning management is required for gourd and bitter gourd. Generally, when pruning, remove the side branches below 5-6 nodes in time, leave 1 to 2 melons on the upper side branches, leave 2 leaves in front of the melon, and leave the main vine 10-11 nodes at the top after topping. Node lateral branches replace the main base to grow. Harvest tender melons in time and remove deformed melons and diseased melons as soon as possible. In addition, try to avoid damaging the vines when pruning. (6) Reasonable use of regulators. In the process of planting, gourd is prone to change, which can be adjusted by using growth regulators, such as chlorphenoxyacetic acid.
